+Fixed the serialization error associated with nested subtypes
+like InputMedia, ChatMember, etc.
+
+The previously generated code resulted in an invalid schema under pydantic v2,
+which has stricter type parsing.
+Hence, subtypes without the specification of all subtype unions were generating
+an empty object. This has been rectified now.
