it looks like the manifest checks are breaking because 6.0.7->6.0.8 but:

1. A hard coded version check in for 6.0.x is extremely fragile
2. In reality that version should really probably be 6.0.9 see [main] Update template versions from dotnet/aspnetcore installer#14488

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

[lewing]

to be explicit, this the 6.0.x version will change with every servicing release (monthly) so the explicit version will break monthly as well

Fixed on main as part of dotnet/sdk@45d4a57
