test: assert ALTER TYPE RENAME rejected on frozen PK UDTs

Browse Source 
Add assertion that ALTER TYPE RENAME is rejected when the UDT is used
as a frozen partition key column. The existing test only covered ALTER
TYPE ADD. This closes the coverage gap from dtest
udtencoding_test.py::test_udt_change_in_partition_key, enabling its
removal.
