Use Bearer/gon for macOS notarization of releases

A tool named gon is used to notarize the macOS release binaries. The original gon tool is now nonfunctional due to its
use of the altool tool, which is no longer permitted by Apple.

Fortunately a fork of gon was created and the migration from altool to notarytool completed in that fork. So the release
workflows are hereby migrated to using the functional fork of gon.
