Documentation for tests/cancun/eip4844_blobs/test_blob_txs.py::test_insufficient_balance_blob_tx_combinations@26332146.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_blob_txs.py::test_insufficient_balance_blob_tx_combinations --fork Amsterdam

Reject all valid blob transaction combinations in a block, but block is invalid.

• The amount of blobs is correct but the user cannot afford the transaction total cost
