…ask execution (#147) Ref: Layr-Labs/eigenlayer-contracts#1610 ## Motivation: As is, BN254 signatures do not sign over a timestamp. To enforce this, we include it within the onchain code to ensure that signatures must sign over a timestamp to prevent mutation issues. This requires the offchain components writing to the BN254CertificateVerifier to use this new procedure. ## Modifications: Update the Executor to use GetGlobalTableUpdateSignableDigest to retrieve the signable digest. ## Result: BN254 certificates now signing over a reference timestamp after execution of the task.

Motivation:
As is, BN254 signatures do not necessarily sign over a timestamp. To enforce this, we include it within the onchain code to ensure that signatures must sign over a timestamp to prevent mutation issues.
