Retain dot-separated wheel tags during cache prune (#13379)

## Summary

If a set of wheel tags includes a dot, this code is treating the part
_after_ the dot as an extension, and thereby failing to detect that the
entry is a symlink to an archive (and thereby removing the archive).

This is all an optimization, so this code just makes it a little
targeted: we skip specific known extensions, rather than anything with
any extension.

Closes https://github.com/astral-sh/uv/issues/13270.
