New hack/xref-helpmsgs-manpages script, added to CI 'gate'
task, runs 'podman [subcommand] --help' and cross-references
against man pages in docs/source/markdown/podman*.1.md
See #5453 and #5460 for instances of the problems the
script has found.
The careful reader will find an alarming number of special-case
bypasses. These are a tradeoff I am making: to get perfect
coverage with no handwaving, it would be necessary to make
drastic changes to some man pages, and I believe those would
be counterproductive.
