Maintenance: Cancel workflow in CI on steps failure

[yannbf]

Issue: N/A

What I did

This PR does a couple of things:

1. Merges the publish and build steps into one. There's no reason to have them run separately, and this saves time (about 20 seconds).

2. Adds a new command which is attached to the critical jobs:
   [ check, lint, unit-tests, script-unit-tests ]

And if any of them failed, it will cancel the entire workflow. This way we don't spend unnecessary time running a bunch of sandbox/e2e tests in case the basic checks are failing, and they should be quickly fixed.

Here's an example when I forced a unit test failure:

Therefore, the entire run took less than 5 minutes instead of 20 minutes (including a bunch of unnecessary sandbox scripts that got executed)

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?

If your answer is yes to any of these, please make sure to include it in your PR.
