f22e5ef6 - Avoid selecting prerelease Python installations without opt-in (#7300)

Avoid selecting prerelease Python installations without opt-in (#7300) Similar to our semantics for packages with pre-release versions. We will not use prerelease versions unless there are only prerelease versions available, a specific version is requested, or the prerelease version is found in a reasonable source (active environment, explicit path, etc. but not `PATH`). For example, `uv python install 3.13 && uv run python --version` will no longer use `3.13.0rc2` unless that is the only Python version available, `--python 3.13` is used, or that's the Python version that is present in `.venv`.
