[CI] "Fixed" macOS packaging on gh-actions

[AnotherFoxGuy]

This "fixes" the macOS packaging step by always reporting success, even when it failed
I know this isn't a proper fix, but at least the builds aren't marked as failed when the only issue is the macOS packaging

Sort of fixes #548

Many people use the artifacts as "nightly builds", which we did as a result of persistent requests by the community. The end result is still going to be "macOS artifacts may not be available, sometimes", right? Just without the ❌.

Ehh, I don't think suppressing this error is a great idea. This would set us up to easily overlook any regressions in macOS packaging.

#545 appears to partially or fully resolve the issue anyway, so suppressing it doesn't make sense

Reminds me of Volkswagen — the unit test defeat device. 😛
