.github: Cleanup actions

Cleanup the .github actions:

- Use the same syntax and/or commands where possible
- Drop unnecessary parameters and steps / commands
- In the all-green job ensure that all CI jobs passed
- Update the naming of jobs
- Review permissions and grant write permission only where
  necessary (repo is set to read-only by default)
- Review installed dependencies (try to fix the failing docs job)
- Run yamllint and fix findings
- Replace deprecated set-output syntax
