fix(uv): fix handling of versions containing plus characters

[acozzette]

Update uv.lock logic to account for versions containing a '+' character

Currently you get an error like this if your uv.lock contains a version with a '+' character in it:

Error in repository_rule: invalid user-provided repo name 'whl_install__mywheel__0_1+20260102': valid names may contain only A-Z, a-z, 0-9, '-', '_', '.', and must start with a letter or a number

This change fixes that by replacing '+' with an underscore in the name we generate. I tried to find all the places where this version-escaping logic occurs and update it to use a new helper function.

@jbedard Thanks! I see that pre-commit check is failing and it looks like perhaps that check expects me to have created a branch in this repo instead of in my own fork. Is that right?

@acozzette I'm not sure what the error is, I haven't had a chance to investigate (feel free to look if you have a chance! 😅)

But we shouldn't expect ever contributor in the world to have permission to commit to https://github.com/aspect-build/rules_py, so that would be a bug on our part if that's the issue.
