Support net6.0 and net8.0

[ricaun]

This PR add support for NET Code 6.0 and NET Code 8.0.

The package gonna have an assembly for both versions.

Until Microsoft.Extensions.DependencyInjection supports net6.0 is a good idea to support as well.

I think that's a bit of presentation problem on the website. The package itself supports .net8:
https://nuget.info/packages/Microsoft.Extensions.DependencyInjection/8.0.0

I'm a bit reluctant to add back .net6 support 3 months before .net6 is out of support. People need to move on. The old package that supports .net6 is still available.

Rollback the version is annoying yes, but the version 4.0.1 has documentation and old version don't have that.

And the package gonna be ready when and if you update the DependencyInjection to version 9.0.0 that does not support net6.0, only net8.0 and net9.0.

When creating a package I always create in the same/lowest version supported by the dependencies, and currently version net6.0 is supported.

Can you describe the scenario where .net6 must be used for new code (the documentation is only relevant for the programmer writing new code)?

The only scenario I use that package is inside some libraries I have, that is build in net6.

I'm already glad that new docs was added and a Guthub Release exists.

I personally would never remove a target framework before the end of the year.
