⬆️(backend) upgrade pylint to 4.1.3

pylint was pinned below 4.0 because pylint-django used to require it.
pylint-django 2.8.0 accepts pylint 4.

pylint 3.x kept too-many-lines pragma line numbers across modules: a C0302
disable in one file could make the check report on the wrong line
in another and fail depending on how files were spread across jobs.
pylint 4.1 resets them per module.
