fix: Tags MUST NOT trigger the GitHub Action.

### Fixed

- Trigger changed to ignore tags. I.e. change of the original trigger `on: [pull_request, push]` which caught also tags. (When running on a tag, actions/checkout runs on refs/tags/vX.Y.Z, so you end up with a detached HEAD, and github.head_ref is empty (it only exists on pull_request).)

 - This GitHub Action automates Prettier formatting across your project, ensuring consistent code styling by creating a new branch for review when necessary. It simplifies integrating Prettier into your workflow, although updates to workflow YAML files in `.github/workflows/` must be done manually.
