A Github Action that installs a specific emacs version
Uses nix-emacs-ci to provide binaries for a number of different Emacs versions.
Since that project uses Nix, Nix will be installed automatically if necessary, along with the "cachix" tool which enables downloads of the cached binaries. If you already have nix and possibly cachix installed, the existing installations will be used.
Note also that only Linux and MacOS are supported, since Nix is not available on Windows.
