After successful review, I plan to make the same change in nuwave/lighthouse#2721.

I also see some projects use this https://github.com/changesets/changesets to automate this further.

I have considered using semantic-release, as it is done in https://github.com/mll-lab/php-utils. What do you think about that?

I've seen that too. Since you have experience with that one, let's pick that one. We only need to make sure that we have a CI action to enforce proper PR title.

We use this in one of our internal projects:

      - uses: amannn/action-semantic-pull-request@v4
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          types: |
            fix
            feat
            chore
