test_max_code_size_fork_transition()

Documentation for tests/amsterdam/eip7954_increase_max_contract_size/test_fork_transition.py::test_max_code_size_fork_transition@9c2813ee.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7954_increase_max_contract_size/test_fork_transition.py::test_max_code_size_fork_transition --fork Amsterdam

Ensure the new max code size limit activates at the fork boundary.
