Man pages: refactor common options: authfile

Refactor the --authfile option.

My suggestion for review:
  1) run hack/markdown-preprocess-review and immediately Ctrl-Q to
     quit out of diffuse, which is completely unusable for this
     many files; then
  2) cd /tmp/markdown-preprocess-review.diffs/authfile
     - this is the directory created by the review script
  3) rm podman-image-sign* podman-log* podman-search.1.md.in
     - because they're essentially identical to podman-create
  4) rm podman-manifest-* podman-push.*
     - because they're 100% identical to podman-kube-play
  5) rm podman-kube-play*
     - because it's apart-from-whitespace identical to podman-build
       (use "wdiff" to confirm)
  6) rm podman-auto-update*
     - because that's the one I chose (hence == zzz-chosen.md)

(You should obviously run your own diff/cmp before rm, to confirm
my assertions about which files are identical).

After all that, you have a manageable number of files which
you can scan, read, diff against zzz-chosen.md, even run diffuse.

This option is IMHO the poster child for why we need this kind
of man page refactoring.

+## NAME
+podman\-manifest\-push - Push a manifest list or image index to a registry
+
+## SYNOPSIS
+**podman manifest push** [*options*] *listnameorindexname* [*destination*]
+
+## DESCRIPTION
+Pushes a manifest list or image index to a registry.
+
+## RETURN VALUE
+The list image's ID and the digest of the image's manifest.
+
+## OPTIONS
+
+#### **--all**
+
+Push the images mentioned in the manifest list or image index, in addition to
+the list or index itself. (Default true)
+
+@@option authfile
+
+#### **--cert-dir**=*path*
+
+Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry. (Default: /etc/containers/certs.d)
+Please refer to containers-certs.d(5) for details. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
+
+#### **--compression-format**=**gzip** | *zstd* | *zstd:chunked*
+
+Specifies the compression format to use.  Supported values are: `gzip`, `zstd` and `zstd:chunked`.  The default is `gzip` unless overridden in the containers.conf file.
+
+#### **--creds**=*creds*
+
+The [username[:password]] to use to authenticate with the registry if required.
+If one or both values are not supplied, a command line prompt will appear and the
+value can be entered.  The password is entered without echo.
+
+#### **--digestfile**=*Digestfile*
+
+After copying the image, write the digest of the resulting image to the file.
+
+#### **--format**, **-f**=*format*
+
+Manifest list type (oci or v2s2) to use when pushing the list (default is oci).
+
+#### **--quiet**, **-q**
+
+When writing the manifest, suppress progress output
+
+#### **--remove-signatures**
+
+Don't copy signatures when pushing images.
+
+#### **--rm**
+
+Delete the manifest list or image index from local storage if pushing succeeds.
+
+#### **--sign-by**=*fingerprint*
+
+Sign the pushed images with a “simple signing” signature using the specified key. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
+
+#### **--sign-by-sigstore-private-key**=*path*
+
+Sign the pushed images with a sigstore signature using a private key at the specified path. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
+
+#### **--sign-passphrase-file**=*path*
+
+If signing the image (using either **--sign-by** or **--sign-by-sigstore-private-key**), read the passphrase to use from the specified path.
+
+#### **--tls-verify**
+
+Require HTTPS and verify certificates when talking to container registries. (defaults to true)
+
+## DESTINATION
+
+ The DESTINATION is a location to store container images
+ The Image "DESTINATION" uses a "transport":"details" format.
+ If a transport is not given, podman push will attempt to push
+ to a registry.
+
+ Multiple transports are supported:
+
+  **dir:**_path_
+  An existing local directory _path_ storing the manifest, layer tarballs and signatures as individual files. This is a non-standardized format, primarily useful for debugging or noninvasive container inspection.
+
+    $ podman manifest push mylist:v1.11 dir:/tmp/mylist
+
+  **docker://**_docker-reference_
+  An image in a registry implementing the "Docker Registry HTTP API V2". By default, uses the authorization state in `$XDG_RUNTIME_DIR/containers/auth.json`, which is set using `(podman login)`. If the authorization state is not found there, `$HOME/.docker/config.json` is checked, which is set using `(docker login)`.
+
+    $ podman manifest push mylist:v1.11 docker://registry.example.org/mylist:v1.11
+
+  **docker-archive:**_path_[**:**_docker-reference_]
+  An image is stored in the `docker save` formatted file.  _docker-reference_ is only used when creating such a file, and it must not contain a digest.
+
+    $ podman manifest push mylist:v1.11 docker-archive:/tmp/mylist
+
+  **docker-daemon:**_docker-reference_
+  An image in _docker-reference_ format stored in the docker daemon internal storage. _docker-reference_ must contain a tag.
+
+    $ podman manifest push mylist:v1.11 docker-daemon:registry.example.org/mylist:v1.11
+
+  **oci-archive:**_path_**:**_tag_
+  An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_.
+
+    $ podman manifest push mylist:v1.11 oci-archive:/tmp/mylist
+
+## EXAMPLE
+
+```
+podman manifest push mylist:v1.11 docker://registry.example.org/mylist:v1.11
+```
