test_invalid_static_excess_blob_gas()

Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_static_excess_blob_gas@2867859a.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_static_excess_blob_gas --fork Amsterdam

Test rejection of blocks where the excessBlobGas remains unchanged but the parent blobs included are not TARGET_BLOBS_PER_BLOCK.

Test is parametrized to MAX_BLOBS_PER_BLOCK and TARGET_BLOBS_PER_BLOCK.
