Enhance reading from .python-version

[krystof-k]

Enhance reading from .python-version file, matching the Pyenv behavior:

• resolves multiple versions from multiple lines
• handles pyenv-virtualenv pointers (e.g. 3.10/envs/virtualenv)
  (see Don't use .python-version for auto-activation pyenv/pyenv-virtualenv#472)
• ignores empty lines and lines starting with #
• trims whitespace

Closes #734 and supersedes #647.

Check list:

• Mark if documentation changes are required.
• Mark if tests were added or updated to cover the changes.

Hello @krystof-k👋,
Thank you for submitting this PR to enhance reading from the .python-version file! 😊
Could you please update your branch with the latest changes from the main branch and run the npm ci, npm run format and npm run build commands to resolve the failing checks related to Basic Validation and dist?
Thank you!

Hi @priya-kinthali, I did, please approve the workflows.

[krystof-k]

@priya-kinthali I fixed the lint, please rerun. I have no idea what the check-dist is.

[krystof-k]

@priya-kinthali sorry, I pushed into a wrong branch. Now it should pass.

[priya-kinthali]

Hello @krystof-k👋,
Thank you for the quick updates!
Please ensure to run npm run build to generate compiled files in the dist/setup and dist/cache-save directories. This should resolve the check-dist failure, as the compiled files are required for the checks to pass.
Also run the npm run test command to run the tests and ensure everything is working as expected.
Additionally, could you also please update the Python versions to the latest ones in the utils.test.ts file, removing the end-of-life versions?
Thank you for your cooperation and effort! 😊
