Feature request: dotnet 10 support

[hjgraca]

Use case

Add dotnet 10 support as a target framework
Powertools will now compiles twice, once for .NET 8.0 and once for .NET 10.0.
The NuGet package will contain both versions, and consumers automatically get the appropriate one based on their project's target framework.

Solution/User Experience

Include net10.0 as target framework
update github actions to use both net8 and net10
