🔧 add .python-version file and update README with Python version requirement for building docs

[azigler]

While setting up the dev environment on Python 3.13 (default M2 Python version) I noticed the wheels dependency failed due to versioning support.

I added a file for a user's local pyenv to pick up the correct version for building the docs. I also included a note in the README:

@PavelLinearB FYI, I'm unable to respond to the microsurvey, it's uneditable for me.

I think it's because you don't have write permissions to the repo.. We'll fix that

@PavelLinearB The check_local_links automation is firing but it's a false positive because this is a README. Do we need to change the rule to not label *.md? Let me know how you'd like to fix.

Also, is check_local_links on the gitStream docs? I don't see an example of that there.

@azigler, This automation we added to protect our docs from internal links pointing to localhost, so it should be applied to README files. We should fix it to remove this false positive, and we can add it to our catalog.

[azigler]

@PavelLinearB In this case, what's triggering the automation was already there (the URL for a user's locally built docs server) and I didn't add it. How do you recommend we point them to their localhost for their docs if we cannot use a local link? I can remove the URL but that feels less helpful.

@azigler I have changed the check so it ignore the specific REAME line, see https://github.com/linear-b/gitstream/pull/731
