release: change dotnet to .NET and loosen version requirements

Update .NET setup tasks to be titled "Set up .NET" instead of "Setup
dotnet." Additionally, change from using a specific .NET version
(6.0.201) to a more general version that aligns with the current version
in use by the project (7.0.x).
