feat:update deployments to use FallbackRoutingHook (#3179)

### Description

- mainnet3, testnet4 should be using fallback routing hooks because it's
more "porous" for first-time deployers of hyperlane to have
merkleTreeHook out of the box

### Drive-by changes

- added overrides to configureHook in basedeployer and setHook in
hookdeployer
- added fetching local rpc first logic in infra/chains and then secrets
rpc if needed. This would mean the forking and live setup will be closer
as the rpc urls will be the same between the two.

### Related issues

None

### Backward compatibility

Yes
