…st `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.
