trag1c 37273cb4bc Add prerelease compatibility check (#8020) ...

## Summary

Closes #7977. Makes `PythonDownloadRequest` account for the prerelease
part if allowed. Also stores the prerelease in `PythonInstallationKey`
directly as a `Prerelease` rather than a string.

## Test Plan

Correctly picks the relevant prerelease (rather than picking the most
recent one):
```
λ cargo run python install 3.13.0rc2
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.17s
     Running `target/debug/uv python install 3.13.0rc2`
