chore: Add missing jobs to CI end (#4963)

`build-docs` and `yarn-project-test` were not requirements of `end`,
which is the job that signals that the CI ended successfully. This
caused PRs to be auto-merged with failing unit tests.

We couldn't flag these two jobs as required in the branch
protection rules for `master` in the project settings, as they are not required to run in the workflow auto-generation if those jobs have a cached artifact.
