Add custom command to show tag annotation to Lazygit Wiki

[pdicerbo]

I tried to the Lazygit Custom Command Compendium but I failed (see here for further details).

I tried to add this custom command to show the tag annotations, maybe it will be helpful to someone..

customCommands:
  - key: 'a'
    context: 'tags'
    command: "git for-each-ref refs/tags/{{.SelectedTag.Name}} --format='%(contents)'"
    output: popup
    outputTitle: "Tag Annotation"
    description: "Show Tag Annotation"

Moreover, if contributions to the Lazygit Custom Command Compendium are not accessible anymore, it could be a good idea to update the relative documentation, just to avoid waste of time by people that try to contribute..

This made me think: instead of having to use a custom command to show the info, shouldn't we just always show it on the right, above the commit log? It could look something like this:

Or are there reasons why this isn't desirable? In some repos I have seen people use really long tag annotations (pasting the changelog for a release into the tag), so you have to scroll down quite a bit to see the commit log. But then, I do feel this information is more useful than the commits, and you can always hit enter if you want so see them.

Also, it might be useful to filter out PGP keys to reduce noise. But apart from that, adding this is not difficult, and I can put up a PR next week.

@pdicerbo I opened a PR: #4663. Please test if this addresses your needs!

Amazing!!
I built the code from source and tested it — it solves exactly my original problem!
If merged, the custom command would become unnecessary. :)
