Update uv python install --reinstall to reinstall all previous versions (#11072)

Since we're shipping substantive updates to Python versions frequently,
I want to lower the bar for reinstalling with the latest distributions.

There's a follow-up task that's documented in a test case at
https://github.com/astral-sh/uv/pull/11072/files#diff-f499c776e1d8cc5e55d7620786e32e8732b675abd98e246c0971130f5de9ed50R157-R158
