ci: Run e2e jobs only if unit-test, lint-*, and pre-commit jobs pass (#796)

**What problem does this PR solve?**:
It's wasteful to run the e2e jobs before the other jobs pass, since
making the other jobs pass almost certainly requires a change to the PR,
which then requires the e2e jobs to run again, discarding the previous
result.
