Use gobject-introspection 1.72 to get around segfaults on Apple Silicon

Currently, Homebrew and MacPorts rely on gobject-introspection 1.70.0.

The version 1.7.2, yet to be released, includes a fix that prevents segfaults on Apple Silicon hardware: https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/301

I will, for now, apply a patch of mine to Glib::Object::Introspection in order to use gobject-introspection 1.72.0. The patch is stored In a GitHub Gist at https://gist.github.com/maelvls/9a4890e7c5adf2309a453d0cdbffaa19.

After merging this PR, the auto-multiple-choice formula should start working on M1 macs.

Future tasks when this PR is merged:

As soon as a new version 1.72 gobject-introspection is released, update the Homebrew formula gobject-introspection.
Open a ticket for Glib-Object-Introspection with a patch since I don't know where to open a PR.

Fixes #55
