Update comment on max checkpoint capacity

…able max

The blob format can encode more blocks (up to ~4095 with all-empty blocks) than
the 2457 provable maximum, but such a checkpoint is unprovable and can only reach
L1 with a malicious committee supermajority, so bounding ingest to the provable
max is intentional. Corrects the prior comment which wrongly implied >2457-block
checkpoints cannot be encoded.
