On ACD 163, it was agreed to bump the target and max blob values from `2/4` to `3/6` for future devnets until we could decide on final mainnet number. This change contains said update, making master pass all the hive tests. The final decision for mainnet cancun is still to be made. --------- Co-authored-by: Felix Lange <fjl@twurst.com>
