Manpage of podman should use U+002d (HYPHEN-MINUS) , instead of converting to U+2010 (HYPHEN), to represent hyphen to prevent confusing

Issue Description

When reading manpages of podman via man podman, user noticed that it's unable to search command options with dashes (e.g. --foobar), but able to search without dashes (e.g. foobar).

Steps to reproduce the issue

Steps to reproduce the issue

1. man podman
2. Press /, enter connection to search, found.
3. Press / again, enter --connection to search, nothing found.

   (This - is U+002d HYPHEN-MINUS, can be entered via a standard keyboard directly.)

4. Press / again, enter ‐‐connection to search, found.

   (This ‐ is U+2010 HYPHEN, can NOT be entered via keyboard directly. please copy & paste this search keyword)

Describe the results you received

(Already described in reproduce steps)

Describe the results you expected

User should be able to search option directly via typing -- on keyboard. And manpage should not use unnecessary non-ASCII characters.

I noticed that the dashes inside the source code of the manpage are normally entered - (U+002d HYPHEN-MINUS):

Should not convert them to U+2010 HYPHEN when generating manapge.

@edsantiago any idea what is going on here?

see https://lwn.net/Articles/947941/ and AFAIK this has been fixed with cpuguy83/go-md2man#105 in go-md2man
The man page on f39 and building from main looks fine for me so I suggest you file this as bug against opensuse as they ar e likely using an older go-md2man.

Or I guess my f39 seems to have this problem patched because cpuguy83/go-md2man#101 is still open. Either way I don't think we can address this in podman as we also use the md source to create html and so on so we cannot really change the source files and need a fix in the generator.
