tests(inferers): remove dead TEST_CASE_ERROR_10 variable

[aymuos15]

Description

Removes TEST_CASE_ERROR_10 from tests/inferers/test_patch_inferer.py. This variable was assigned but never referenced: the error-cases parameterized expand list uses only ERROR_0 through ERROR_9, and grepping the module confirms it has no readers beyond its own definition. It was also byte-identical to TEST_CASE_ERROR_7.
