Diagnostic ID: CA1002: Do not expose generic lists

Analyzer source

NuGet Package: Microsoft.CodeAnalysis.NetAnalyzers

Version: 7.0.0

Describe the bug

This rule prevents the use of Generic Lists for inheritance issues, however sealed classes cannot be inherited, so the rule should not apply. I suggest creating an exception for sealed classes.

Steps To Reproduce

1. Create a 'sealed' class.
2. Create a property of type Generic List.
3. Observe the analyzer give error CA1002.

Expected behavior

Analyzer should not cite CA1002 on sealed classes.

Actual behavior

Analyzer cites CA1002 on sealed classes.

Additional context

None
