crypto/bn256: switch to gnark again #32659 (#1552)

Browse source 
We recently update our default implementation to gnark in
https://github.com/ethereum/go-ethereum/pull/32024
Then we found a consensus issue and reverted it in
65d77c5129
We fixed the consensus issue and have been fuzzing it more since then in
https://github.com/ethereum/go-ethereum/pull/32055/files
https://github.com/ethereum/go-ethereum/pull/32065
https://github.com/ethereum/go-ethereum/pull/32055/files

So I think now is the time to update it back to gnark
