v6.3.1 🌈 Do not warn when version not in manifest-file

Changes

This is a hotfix to change the warning messages that a version could not be found in the local manifest-file to info level.

A setup-uv release contains a version-manifest.json file with infos in all available uv releases. When a new uv version is released this is not contained in this file until the file gets updated and a new setup-uv release is made.
We will overhaul this process in the future but for now the spamming of warnings is removed.
