CI can use wrong Python version in some cases

[Pijukatel]

See following log screenshot which proves that Poetry can override Python version that was intended to be used by the CI:

Run pipx install --python 3.9 poetry
creating virtual environment...
installing poetry...
done! ✨ 🌟 ✨
  installed package poetry 2.0.1, installed using Python 3.9.21
  These apps are now globally available
    - poetry
poetry install --all-extras
The currently activated Python version 3.9.21 is not supported by the project (^3.10).
Trying to find and use a compatible version. 
Using python3.12 (3.12.3)

lets just add a PR check to ensure the python version is matching what it should be
