Bump NUnit.Analyzers upper limit to v3.9

[nowsprinting]

When NUnit.Analyzers were registered; they only worked up to v3.3 on Unity, but now they support up to v3.9.

v3.10 and later are for NUnit4 and are therefore excluded.

How do you know that? The readme file in the repository still says:

If your Unity project is made by Unity 2021.2 or later, then use NUnit.Analyzers v3.3 (v3.4 or later of the analyzers does not work with Unity).

I added this note at the time when the Unity manual page did not include the supported Roslyn version.
nunit/nunit.analyzers#489

I'm planning to submit a PR to change this.

I mean, how do you know that NUnit.Analyzers <= 3.9 works with Unity? Because you've tested it yourself?

Yes, I tried in Unity 6000.0.50f1.

Additionally, the latest version of NUnit.Analyzers, v4.10, use Microsoft.CodeAnalysis.CSharp v3.11.0, so this should also work with Unity 6.
