Investigate CI solution for ensuring proper commit format for the first commit of PRs

Describe the enhancement or change
We pretty often run into issues where improper commit message formatting causes a release to not happen when expected.

This could be resolved by enforcing formatting on every commit like we do in core, but that would be a bit of an inconvenience for all but the first commit since we squash on merge and the commit message format after the first commit doesn't matter.

We may be able to use https://github.com/wagoid/commitlint-github-action or something similar to do this.

Also, if we do find a good solution here we should probably replicate it in the extension repos.

No se nombran archivos ni pruebas. Empieza revisando la configuración de CI del repositorio y evaluando commitlint-github-action o un enfoque similar para comprobar únicamente el primer commit de un pull request. Se considera completado cuando se haya documentado o implementado una comprobación viable que preserve el comportamiento de squash-merge y se haya decidido si puede replicarse en los repositorios de extensiones.
