Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description

Witten in podman info man page, podman info --debug, -D shows addtitional information.

   --debug, -D
       Show additional information

However, I don't see any difference from podman info.
I would like to know the meaning of this option.
(Do we have a plan to add feature about --debug, -D in future?)

It is definitely not used at the moment. Maybe it was used at some point?
@containers/podman-maintainers PTAL

AFAICS, #5738 changed the --debug flag to a nop.

What --debug did pre v2 was adding the version: information:

  Version: 4.2.0-dev

But that is now added unconditionally. I think we can hide the --debug flag and update the GitHub-issue template.

It's a NOP since Podman v2.0 (containers#5738).

[NO NEW TESTS NEEDED] - does not change behavior.
