This caches the builds of contracts and mocks in order to save up to 3m30sec of PR check execution in current state.

• chore: fix CI and refactor patch deployment script #16

I see what you're trying to do. I'll pre-approve on the grounds that you de-duplicate build-and-test.yml and main.yml.

In the future, when a PR is built on top of a non-main branch, make the PR target the non-main branch. Then, as long as you merge the target, non-main branch to main first, Github will automatically update the target of this PR to the main branch.

For this PR I simplified the diff using: chore/deploy-script-refactor-patch...chore/cache-workflow-builds

@MantisClone It was a draft with no review request for that reason, I wanted #16 to be merged first.

I saw it was a draft. But I also saw you mention it in Slack so I wanted to optimistically approve to not block you further.
