An attempt to fix flaky zksync test

- Upgraded several development dependencies related to Hardhat and zkSync:
  - `@matterlabs/hardhat-zksync-deploy` from `^1.5.0` to `^1.6.0`
  - `@matterlabs/hardhat-zksync-node` from `^1.1.1` to `^1.2.1`
  - `@matterlabs/hardhat-zksync-verify` from `^1.6.0` to `^1.7.1`
  - `zksync-ethers` from `6.12.1` to `6.15.3`
- Refactored the test setup in `SafeToL2Setup.spec.ts` to retrieve the deployed contract instance using `getContractAt` instead of deploying a new instance, enhancing test reliability and efficiency.
