Update version of NUnit related packages

I hitting bunch of exceptions during execution of dotnet test tests/FSharp.Compiler.Service.Tests/FSharp.Compiler.Service.Tests.fsproj on Linux with only .NET 6 installed.

System.ArgumentException: Unknown framework version 6.5 (Parameter 'version')

In spirit of #9947 maybe would be better to migrate these tests to XUnit

While I was there I remove NUnitLiteVersion which is not used anywhere.

IIRC, this error happens when there are some issues with tests themselves, and has nothing to do with nuget packages. Tests are passing on Linux in the latest main.

[kant2002]

The exception did not fail test (which is wierd). IF you go to latest build from main branch, in the Linux leg 'Build/Test' task, and look for line 2395 you will see same exception. And tests will pass (I assume that this is because tests which failed to discover are skipped).

I assume that issue which I was hitting is nunit/nunit#3565 which according to log was fixed in NUnit 3.13

[vzarytovskii]

Hm, interesting, I've only been hitting it when some tests were failing.

[kant2002]

So question, should I just bump version of NUnit (other dependencies most likely unrelated, just did not see point keep infra dependencies not updates). Or should I try to move tests to XUnit. Better tactical decision obviously just bump versions, but what's long term plan. Is move to Xunit freezed right now?

[vzarytovskii]

Bumping version is fine. Long term plan is to continue moving tests to xunit.
