Remove NoMono

[asbjornu]

Resolve #2316 by removing the NoMono test category.

Description

It may be that we can do without the NoMono test category now. This PR tests that assumption.

Related Issue

Resolves #2316.

Motivation and Context

If we don't need to filter out tests to run, we shouldn't.

Ok, it seems like we need to await #3002 for this to be successful as a few former NoMono categorized tests are still failing on net48 on macOS.

@asbjornu I think we could release a new version 5.9.0 that contains the nullable fixes I did and then we can merge the PR with the sunset of net48 and net50 - thoughts?

[asbjornu]

Are you suggesting to sunset net48 and net50 in 5.9?

[arturcic]

No, there are some changes that were merged related to nullability, that one should get a minor version - 5.9. Right after that we can merge the sunset net48 and net50 into main and that will be version 6.0 as it's a breaking change.

Ok, agreed. We need to get a speed on the new CLI that we also want to break in v6, then. 😅

Or we can push the CLI to v7.0 to be more in line with the .net version :D

[asbjornu]

True, that's also an option. Do we have any other, lower-hanging fruits of breaking changes we want to roll into v6? Or said reversely, which of the issues in the v6 milestone besides new CLI should we postpone to v7?

I moved those related to CLI to v7, the others should stay in v6 I think, can you check as well?

[asbjornu]

Yeah, I agree.
