Add alias for dotnet workload repair command #3483
Description
dotnet workload repair - Repairs workloads installations. Introduced with .NET 6 SDK.
The dotnet workload repair command reinstalls all installed workloads. Workloads are made up of multiple workload packs and it's possible to get into a state where some installed successfully but others didn't. For example, a dotnet workload install command might not finish installing because of a dropped internet connection.
