Current version of maintertools

Describe the bug

Hey guys I saw that we havent update maintainer-tools isort version which leads to the error described here

To Reproduce

Current Version: just take OCA branch 16.0 and try using pre-commit on it.

Steps to reproduce the behavior:

1. Get an OCA branch version 16.0
2. using the maintainer-tools try running pre-commit run -a
3. error pops

Expected behavior
pre-commit run needs to run without errors so the soln is to update the .pre-commit-config.yaml isort to new version e.g > 5.12.0

Additional context
So its an isort upgrade issue, latest isort will fix the error

This was tackled in OCA/oca-addons-repo-template#184.

Do pipx run copier -f update for upgrading the repo to latest copier template and do a PR fixing it.
