Set comment email as Email Address datatype

[bjarnef]

I think it would be great to add an "Email Address" datatype instance:

and set this as datatype instead:
https://github.com/umbraco/Umbraco.UIBuilder.Demo/blob/main/src/Umbraco.UIBuilder.Demo/UmbracoBuilderExtensions.cs#L47

.AddField(c => c.Email).SetDataType("Email Address").SetValidationRegex("[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+")

or the guid overload method in umbraco/Umbraco.UIBuilder.Issues#67

Eventually it could add constants like this in core:
