FIX: Fix pre-commit CI

[kurlov]

pre-commit CI step fails with:

Run pre-commit/[email protected]
Run python -m pip install pre-commit
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

GH actions uses ubuntu-latest and GH recently started to migrate ubuntu version. The new ubuntu version comes with new python and pip. The new pip fails to install system wide packages by default to follow PEP-668. Technically it should not be an issue because this repo CI setups a dedicated python so it should be used to install pre-commit instead of default ubuntu python. The problem is that this setup python step do not do anything by default. Here are the logs:

Run actions/setup-python@v5
Warning: Neither 'python-version' nor 'python-version-file' inputs were supplied. Attempting to find '.python-version' file.
Warning: .python-version doesn't exist.
Warning: The `python-version` input is not set.  The version of Python currently in `PATH` will be used.

This PR fixes it and make setup-python step prepare env for the pre-commit installation
