patchpal 0.4.0: (new formula)

Initial homebrew packaging.

This is software developed by some folks at Red Hat, looking to improve
the patch backporting experience, even for those using macOS. It's a
rust-based frontend that can be run entirely without the backend, but can
also hook into a python-based backend AI server that helps provide AI
assistance with backporting patches from a development branch to an older
stable maintenance branch, such as, say, from the upstream Linux kernel
branch to an old Red Hat Enterprise Linux kernel branch.
