test_invalid_excess_blob_gas_target_blobs_increase_from_zero()

Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_excess_blob_gas_target_blobs_increase_from_zero@88e9fb8f.

Generate fixtures for these test cases for Osaka with:

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

Test rejection of blocks where the excessBlobGas increases from zero, even when the included blobs are on or below target.

Test is parametrized according to [0, TARGET_BLOBS_PER_BLOCK new blobs.
