That PR targeted release/9.0.2xx, so it never made it into release/9.0.1xx.
The problematic line that that was trying to fix is here:
sdk/src/Cli/dotnet/commands/dotnet-workload/install/WorkloadGarbageCollector.cs at v9.0.103 · dotnet/sdk. Note that it is still present in release/9.0.1xx.

I believe users will hit this if they do the following:

1. They install a workload set with a fourth version part (9.0.102.1 in this case)
2. They try to do garbage collection for any reason

The reason that line fails in that scenario is that we tried to parse a 4-part version into a ReleaseVersion. ReleaseVersions only support up to three version parts. We only do that parsing as part of trying to sort the workload set versions, however, so there's no reason we need to parse them into ReleaseVersions if we can otherwise compare them. That's what the below fix does.

The fix is to backport #45263
