Describe the feature or problem you'd like to solve

When creating GitHub releases with the gh release create command, I would like to use messages from pre-existing annotated Git tags as release notes.

It seems like there's a way to do this interactively:

Can I noninteractively create a release with the Git tag message?

There's a --notes option, but it accepts a string and doesn't seem to auto-populate with the Git tag message. I could use a git show command I guess, but that would include additional metadata like the commit diff.

There's also a --notes-start-tag option, but I think that's supposed to be used with --generate-notes to automatically generate release notes based on a list of PRs, not tags (?)

Proposed solution

Add an option --notes-from-tag, which would automatically populate the release notes with the message in the tag specified by gh release create [<tag>].
