[CAL-3655] Add API build cache in CI pipeline

[keithwillcode]

We now build API v1 and v2 on every PR but they are not being cached, making future re-runs of the CI pipeline that have previously failed due to test flakes slower.

Update https://github.com/calcom/cal.com/blob/main/.github/workflows/api-v1-production-build.yml and https://github.com/calcom/cal.com/blob/main/.github/workflows/api-v2-production-build.yml to do what https://github.com/calcom/cal.com/blob/main/.github/actions/cache-build/action.yml is doing in terms of caching.
