Documentation for tests/amsterdam/eip7954_increase_max_contract_size/test_fork_transition.py::test_parent_max_code_size_across_fork@5c024cbb.

Generate fixtures for these test cases for Amsterdam with:

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

Ensure previous max code size works after transition.
