test_invalid_zero_excess_blob_gas_in_header()

Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_zero_excess_blob_gas_in_header@e9958ed2.

Generate fixtures for these test cases for Osaka with:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_zero_excess_blob_gas_in_header --fork Osaka

Test rejection of blocks where the excessBlobGas in the header drops to zero in a block with or without data blobs, but the excess blobs in the parent are greater than target.
