Man pages: refactor common options: --volume

This one is a nightmare, because --volume has been edited
in four different files throughout the years (five if you
count podman-build, which I am not including in this PR).
Those edits have not always been done in sync.

The list of options was reordered 2022-06-28 by Giuseppe in #14734,
but only in podman-create and -run (not in podman-pod-*). No
explanation of why, but I'll assume he knew what he was doing,
and have accepted that for the reference copy.

There was also a big edit in #8519.

The "Propagation property...bind mounted" sentence first appeared
in pod-clone, in #14299 by cdoern, with no obvious source of where
it came from. I choose to include it in the reference copy.

The "**copy**" option seems to work in pod-create, so I'm including
it in the reference copy. Someone please yell loudly if this is
not the case.

The "disables SELinux separation for containers used in the build",
no idea, changed that to just "for the container/pod"

The "advanced users / overlay / upperdir / workdir" paragraph
makes zero sense to me, but hey, I assume it applies to all
the commands, so I put it in the reference copy.

Finally, there's still a mishmash of backticks, asterisks, underscores,
and even quotation marks. Someone is gonna have to perform major
cleanup on this one day, but at least it'll be in only one place.
