Remove GH action warnings

[anth-volk]

Fixes #229

Solution: Upgraded EndBug/add-and-commit, used within push.yml, to version 9, as described in this issue solution within the EndBug/add-and-commit repo.

Version 9 does introduce two breaking changes (described here): the action fails if git commit fails, and the action will not attempt to recreate tags when failing to push them. However, it was not possible to test for these two cases.

Thanks @anth-volk! Could you please:

• Replace Fix for: #229 with Fixes #229 in the PR description; this specific syntax will link the PR to the issue so merging it will close the issue
• Populate changelog_entry.yaml per other recently merged PRs to pass the version check CI test.

[anth-volk]

Ah, my apologies, I should've reviewed the PR requirements before requesting

[anth-volk]

I'm sorry, I'm not understanding the changelog system. I altered changelog_entry.yaml as instructed, adding the details of the relevant changes, but the version check failed, indicating that I hadn't also updated CHANGELOG.md. Is this not automatically generated? I was under the impression that changelog_entry.yaml was automatically pushed to the top of the file, with the relevant change type updating the relevant portion of the semantic version number. Should CHANGELOG.md (and changelog.yaml, for that matter) also be manually updated?

[MaxGhenis]

You populated the changelog entry correctly, just this minor change and git pull upstream master will do it. The action fails if the branch is behind upstream/master.

[anth-volk]

This should now be properly synced with upstream/main and integrate the typographical changes suggested; however, I'm still receiving the same issue when running checks. I'm going to try to dive into this and figure out what it might be.

[anth-volk]

It appears that, when forking, Git does not also copy upstream's tags, so after fetching tags from upsteram master, I should now be able to pass the has-functional-changes GitHub workflow

Sorry @anth-volk - could you re-file from a branch? I just gave you write access- happy to help if unclear

[nikhilwoodruff]

Actually... this is mergeable- I've just checked the file change. Thanks Anthony!

[anth-volk]

Great, thanks! Glad to have finally gotten this one in haha. Thanks for all the support, @nikhilwoodruff and @MaxGhenis.
