CA1822 - Support for TUnit

Analyzer

Diagnostic ID: CA1822

Describe the improvement

Currently, CA1822 provides exclusions when attributes from XUnit, MSTest, and NUnit are applied to a method. I am in the process of migrating to TUnit, a new testing framework; but since it does not use the same attributes, [Test] methods are being flagged by CA1822.

It would be helpful to either/both:

1. have a parameter in the .editorconfig to add additional attributes to the skipped list
2. add TUnit.Core.TestAttribute, TUnit.Core.BeforeAttribute, TUnit.Core.BeforeEveryAttribute, TUnit.Core.AfterAttribute, TUnit.Core.AfterEveryAttribute` to the exclusion list.

Describe suggestions on how to achieve the rule

1. Am not familiar enough with the process to provide clear directions on how to improve. Expected .editorconfig might look something like:

dotnet_code_quality.CA1822.excluded_attributes = T:TUnit.Core.TestAttribute, T:TUnit.Core.BeforeAttribute

2. • The above listed attributes added to WellKnownTypeNames
   • The above listed attributes added at: https://github.com/dotnet/roslyn-analyzers/blob/main/src/NetAnalyzers/Core/Microsoft.CodeQuality.Analyzers/QualityGuidelines/MarkMembersAsStatic.cs
