Description:
The SDK ships with supporting a set of workloads (Wasm, MAUI, Aspire, and potentially more in the future). The setup-dotnet action should support these as further instructions to actually 'setup' the full dotnet environment as expected, not automatically, but opt-in.

uses: actions/setup-dotnet@v5
with:
  dotnet-version: 8.0.x
  workloads: [maui, aspire]

The expectation is that after SDK would be installed that then command would run dotnet workload update (to ensure manifests are updated) and then dotnet workload install on each item in the array

Justification:
Workloads are a primary way to get additional platform SDK tools and dependencies for key .NET frameworks.
