Documentation for tests/shanghai/eip4895_withdrawals/test_withdrawals.py::test_large_amount@02aafd78.

Generate fixtures for these test cases for Bogota with:

fill -v tests/shanghai/eip4895_withdrawals/test_withdrawals.py::test_large_amount --fork Bogota

Test withdrawals that have a large gwei amount.

Test such that that (gwei * 1e9) could overflow uint64 but not uint256.
