scripts: revised linting script (#2737)

The new version uses our `log.sh` helper to simplify logging
significantly. Moreover, the script was adjusted to the current style
and the GitHub workflow was streamlined. The workflow is ot providing
the version anymore (which was useless anyway), and has been compacted.
