'dotnet_style_require_accessibility_modifiers = always' doesn't work for interface members

[TessenR]

Version Used:

Microsoft Visual Studio Professional 2022
Version 17.10.0 Preview 6.0
VisualStudio.17.Preview/17.10.0-pre.6.0+34825.169
Microsoft .NET Framework
Version 4.8.09037

Steps to Reproduce:

Set the option in editorconfig:

dotnet_style_require_accessibility_modifiers = always:error

Compile the following code:

public interface IInterface
{
  void Method();
}

Diagnostic Id:

IDE0040 Add accessibility modifiers

Expected Behavior:
There should be an error indicating that a public modifier for void Method() is required

Actual Behavior:
There's no IDE0040 inspection. dotnet_style_require_accessibility_modifiers = always is behaving the same as dotnet_style_require_accessibility_modifiers = for_non_interface_members

Notes:
This code looks outdated, there's already a version of C# that supports modifiers on interface members:

roslyn/src/Analyzers/CSharp/Analyzers/AddAccessibilityModifiers/CSharpAddAccessibilityModifiersDiagnosticAnalyzer.cs

Lines 56 to 65 in f618852

	#if false
	// Add this once we have the language version for C# that supports accessibility
	// modifiers on interface methods.
	if (option.Value == AccessibilityModifiersRequired.Always &&
	member.IsKind(SyntaxKind.InterfaceDeclaration, out typeDeclaration))
	{
	// Only recurse into an interface if the user wants accessibility modifiers on
	ProcessTypeDeclaration(context, generator, option, typeDeclaration);
	}
	#endif
