Removes pylint from our toolchain (apache/airflow#16682)

We've agreed during the voting process that Pylint support
should be disabled: https://lists.apache.org/thread.html/r9e2cc385db8737ec0874ad09872081bd083593ee29e8303e58d21efb%40%3Cdev.airflow.apache.org%3E

This PR:

* removes all # pylint comments
* removes pylint pre-commits and related scripts/files
* removes CI jobs running pylint checks
* removes documentation about pylint
* removes unnecessary #noga (adds pre-commit for that)
* fixes some remaining pydocstyle errors after removing #noqa's
