ci: add CI to auto validate deployment scripts (#1360)

**Motivation:**

curently there's no ci coverage for deployment scripts. scripts can be
only validated manually by devs offline by running `zeus test` on
terminal

pain points:
1/ no quality control of scripts that got merged in
2/ manual testing is time intensive and not scalable

i feel these pain points as i'm writing deploy scripts of elip5 (v1.6.0
release)

**Modifications:**

add a new ci workflow to auto validate deployment scripts under
/scripts/release/ in all 5 envs, currently mainnet, testnet, preprod.
testnet-sepolia and testnet-hoodi to be added

the ci will only run if a pr touches anything under /scripts

**Result:**

- quality control is put in place for all deployment scripts
- fully automated, to save devs time
