installer: Updating to VS16.8.4 doesn't correctly uninstall .NET SDK 5.0.101

Updating from 16.8.3 to 16.8.4. Having 16.9P3 installed alongside.

Symptom: In control panel, SDK 5.0.102 (from VS) and 5.0.200-preview (from VS) exist as expected. SDK 5.0.101 (not from VS) exists unexpected.

Uninstalling the entry doesn’t remove 5.0.101 SDK.
