BUG: mamba 无法为已下载的包应用 repodata 补丁

Now that `conda{,-build} 26.1` came out, I did `mamba update --all` again, and ran into the same breakage (because I hadn't noticed that mamba had wrongly updated to `py-rattler v0.22` again). Only this time, the repodata patch should have forbidden mamba updating `py-rattler` even for the `_0` build of `conda smithy 3.54.2` I had already installed.
