TypeExtensions.ToTypeString does not support generic types definitions

[OleksiiD]

Describe the bug

TypeExtensions.ToTypeString throws the ArgumentOutOfRangeException exception for generic type definitions.

TypeExtensions.ToTypeString(typeof(IDictionary<,>))

The easiest solution would be to add the following code in the FormatDisplayString method:

if (type.IsGenericTypeParameter)
{
    return type.Name;
}

@OleksiiD I've transferred your issue to the proper repository here for the .NET Community Toolkit. To help us better understand, what led you to originally file it in the Windows Community Toolkit repository? Thanks!
