.github/workflows/run-tests.yaml: codecov/codecov-action@v3: Adjust fail_ci_if_error

Setting `fail_ci_if_error` to `false` is more suitable for a non-organizational repository.

Experiencing frequent issues with Codecov,
especially on public uploads without a secret, despite what's advertised.

Opting for a more reliable action workflow, even if it means some reports
might be less informative, rather than having the Actions fail due to these issues.
