Support required modifier

It would be nice if the required modifier could be considered a way of making properties required. You could think of the following:

class Model
{
    public required string MakeRequired { get; init; } // When analyzing this property, add a default instance of a RequiredAttribute to the list of validation attributes/

    public required int ValueType { get; init; } // Ignore, adding a required attribute will not change a thing.
  
    public required string? NullableReference { get; init; } // Ingore, it must be set, but null is considered valid option.

    [Any]
    public required int[] SomeObject { get; init; } // Ignore, AnyAttribute inherits from RequiredAttribute and should prevail.
}

What do you think?

The issue names no files or tests, but provides C# property examples for the proposed behavior. Start by tracing how MiniValidation analyzes property metadata and validation attributes, then compare non-nullable reference types, value types, nullable references, and existing RequiredAttribute-derived attributes. Done means the required modifier is handled according to all four examples with coverage for each case.
