Add Arch Linux package for build-magic #88
Description
Is your feature request related to a problem? Please describe.
Build-magic has packages for debian/ubuntu/mint and fedora/centos/rhel. Need to add a package for arch/manjaro.
Describe the solution you'd like
The PKGBUILD file and makepkg process should be automated in the package.yaml file in the build-magic repo, and should upload the resulting .zst file to the GitHub release.
See https://wiki.archlinux.org/title/creating_packages for more info on creating Arch Linux packages.
See https://github.com/cmmorrow/build-magic/blob/main/package.yaml for how the build-magic packages are built for debian and centos.
Note: Do not commit GitHub secrets to the repo!
