Add a warning to the CreateContentFromBlueprint method xml docs

[lauraneto]

Closes #19352

A proper fix was done for V16 in #19528, but for V13 it would be more tricky as we wouldn't want to introduce new methods or a behavioral change. Instead, a remark was added to the method's xml docs to warn users.

Thanks @lauraneto. Looks good to me and is a sensible approach for 13 I believe.
