chore: Update to setup-dotnet v4 and use global.json for versioning (#9546)

Aligns all CI workflows to use setup-dotnet action v4, replacing v3,
and switches from hardcoded .NET version to using global.json for
version management. Improves consistency and future maintainability
of .NET version selection across workflows.
