Add anchors for flag names on docs.podman.io

Change the docs markdown so that flag names will be h4 headers.
Sphinx will automatically add anchors to headers. Add css to
make sure the flag names are not to big compared to the text.

The man pages also still renders fine but it looks a bit different.
