chore: refactor CreateMerkle scripts to deploy merkle lockup instances

[smol-ninja]

The objective of having CreateMerkleLL and CreateMerkleLT scripts is to deploy instances of merkle lockup and verify them on-chain so that etherscan can automatically verify other lockups deployed by the users.

However, its time consuming to construct the parameters of run command. This PR makes it easier to achieve the same objective by setting all parameters inside the script itself.

FOUNDRY_PROFILE=optimized \
forge script script/CreateMerkleLL.s.sol \
--broadcast --etherscan-api-key $ETHERSCAN_API_KEY \
--rpc-url mainnet --sig "run()" \
--verify -vvv

What if we merge these two? Or add a new one CreateMerkleCampaigns to deploy both LL and LT in a single run. wdyt?

[smol-ninja]

Etherscan verification is not totally reliable so I'd keep them separate. If combined into a single run and one of the verifications fails, it would add a bit of a work to re-run one script while skipping the other.

Got it, thanks for explaining
