Generate fixtures for these test cases for Shanghai with:

Shanghai only:

fill -v tests/shanghai/eip4895_withdrawals/test_withdrawals.py::test_self_destructing_account --fork=Shanghai --evm-bin=/path/to/evm-tool-dev-version

For all forks up to and including Shanghai:

fill -v tests/shanghai/eip4895_withdrawals/test_withdrawals.py::test_self_destructing_account --until=Shanghai

Test withdrawals can be done to self-destructed accounts. Account 0x100 self-destructs and sends all its balance to 0x200. Then, a withdrawal is received at 0x100 with 99 wei.
