Add documentation for python

[samfreund]

Description

This adds docs for python. The docs can be seen at https://pydocs.photonvision.org/

This is accomplished using mkdocs to scan the code and auto-generate documentation.

Meta

Merge checklist:

• Pull Request title is short, imperative summary of proposed changes
• The description documents the what and why
• If this PR changes behavior or adds a feature, user documentation is updated
• If this PR touches photon-serde, all messages have been regenerated and hashes have not changed unexpectedly
• If this PR touches configuration, this is backwards compatible with settings back to v2024.3.1
• If this PR addresses a bug, a regression test for it is added

The param and return tags are still rendered as plain text

This is happening because mkdocs doesn't support reST style tags, which means we might want to switch to Sphinx - Sam
