Properly handle authentication for 302 redirect URLs (#12920)
uv was failing to authenticate on 302 redirects when credentials were
available. This was because it was relying on `reqwest_middleware`'s
default redirect behavior which bypasses the middleware pipeline when
trying the redirect request (and hence bypasses our authentication
middleware). This PR updates uv to retrigger the middleware pipeline
when handling a 302 redirect, correctly using credentials from the URL,
the keyring, or `.netrc`.
Closes #5595
