Incorrect CustomValidationAttribute remarks

[hrobertson]

Content: https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.dataannotations.customvalidationattribute.method?view=netcore-2.2
Content source: xml/System.ComponentModel.DataAnnotations/CustomValidationAttribute.xml

The remarks for the Method property of CustomValidationAttribute incorrectly state that the specified method must return a Boolean and takes a ValidationResult out param. In .Net Core 2.2 at least, it must return a ValidationResult.

Maybe the signature is different in different languages?

Additionally, it would be preferable to have the valid signatures listed as code snippets rather than described in text.

Thank you for your feedback @hrobertson.

@lajones, @divega, @ajcvickers can you help with this issue? Are there differences in behavior between .NET Framework and .NET Core for this API? Thanks.
