Fix AcroFormField Subtype setter to be a true no-op

The setter was storing values, which caused tests to fail because the
stored value would appear in the PDF output. Tests expect setting
radioGroup.Subtype = "Form" to be silently ignored without affecting
the computed value returned by the getter.

This changes the setter to be a true no-op (empty function), preventing
the "Cannot set property which has only a getter" error while preserving
the original behavior where assignments are silently ignored.
