[WIP] feat: contracts publishing in CI

[erikburt]

Do not merge

Proof-of-concept workflow for publishing contracts to NPM through CI.

• Takes the general flow from CCIP - https://github.com/smartcontractkit/ccip/blob/ccip-develop/.github/workflows/solidity.yml
• Utilizes https://github.com/smartcontractkit/.github/blob/main/actions/ci-publish-npm/action.yml instead

Left to do:

• [ ] Set an environment for the publish jobs so secrets publishing secrets are further gated
• [ ] Set up branch protection rules for gh environment
• [ ] Test via dry-run
• [ ] Have secrets added to repository
• [ ] Test via dry-run again
• [ ] Remove dry-run flag and "test" during next release cycle

I see that you haven't updated any CHANGELOG files. Would it make sense to do so?
