1328 update prover permissions on the light client contract via openzeppelin defender and safe wallets

[alysiahuggins]

Closes #1328

Open Questions/TODOs

• TODO: It currently depends on a SEPOLIA_RPC_URL and Sepolia Deployments of the Safe Account/ Multisig Wallet and the Light Client Contract
• OQ: The steps required to test require manual UI interaction e.g. creating a mutlsig wallet, setting up an open zeppelin account. It's not trivial to test with a forked/private network because the Safe SDK requires mainnet or supported testnets (learn more about this in the Readme)
• TODO: Socialise the use of multisig wallets, determine the threshold and owners

This PR:

• provides the ability to enable/disable permissioned prover mode on the light client contract via a multisig wallet
• it uses the SafeSDK to accomplish the above
• this code can be extended to perform any admin/multisig wallet only tasks
• the ability to deploy a smart contract to a live network without requiring a license (as was previously the case with OpenZeppelin but fixed with https://github.com/OpenZeppelin/openzeppelin-foundry-upgrades/pull/43)

This PR does not:

• provide a local testing environment for openzeppelin/safe interactions

Key places to review:

• ./contracts/script/multisigTransactionProposals/safeSDK (the files in here are newly added)
• feedback on the workflow required to get this to work and how it can be improved despite the limitation of not being able to use forked/private networks

How to test this PR:

• see the readme (./contracts/script/multisigTransactionProposals/README.md)

Things tested

• util functions in utils.ts via yarn jest
• approving (set permissioned prover and disable permissioned prover) transactions via a multisig wallet. You can see the transactions on sepolia here e.g. this transaction https://sepolia.etherscan.io/tx/0xddbc669b95b7ad0d2a6045d06ebba6bbf32e05f4aeffb936814094a2a6c7b2d1 is where one of the multisig signers, 0xB22167f12C232e825D26ffbb3780E024c506664E, sent a transaction via the safe multisig account 0xc56fA6505d10bF322e01327e22479DE78C3Bf1cE, so that 0xc56fA6505d10bF322e01327e22479DE78C3Bf1cE can be set as the permissioned prover.

Safe account and multisig wallet has been used interchangeably.
