🔥 Stop failing the test if code coverage goes down

We currently run tests and check code coverage in the same workflow,
and fail if the code coverage goes down. But our current coverage is fairly
limited (< 20%) so we have a lot of failures from changes to code that
currently does not have any tests.

Let's still check the code coverage, but disable the `fail_on_error` so it
doesn't mask errors in the tests. Once we improve coverage to cover more areas,
we can re-enable this.
