Ensure PR titles follow conventional commits

[BigLep]

Done Criteria

Ensure each PR title follows conventional commit conventions. If it doesn't, a CI check should fail.

Why Important

release-please only includes commits that follow conventional commit conventions. We want all of our PRs getting indicated in the release-please list, which means all PRs that are going to be squashed should have conventional commits.

Notes

#186 is an instance where this was missed and #388 was done to correct it.
