test_beacon_root_equal_to_timestamp()

Documentation for tests/cancun/eip4788_beacon_root/test_beacon_root_contract.py::test_beacon_root_equal_to_timestamp@21507778.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4788_beacon_root/test_beacon_root_contract.py::test_beacon_root_equal_to_timestamp --fork Amsterdam

Tests the beacon root contract call where the beacon root is equal to the timestamp.

The expected result is that the contract call will return the parent_beacon_block_root, as all timestamps used are valid.
