Update Github Actions workflow for MacOS builds

* Remove MacOS 11 builds because it is no longer support by Apple or
  Homebrew
* Add MacOS 13 debug builds
* Update release build to MacOS 12
* Remove `brew update` from release build. This reverts 9f943a3 because
  the fix for the Homebrew bug that it addressed is already available.
  It is also equally likely for an up-to-date version of Homebrew to
  cause build failures so for now it is convenient to save time by
  avoiding the update.
