Recognize Homebrew Core formulae as packages

**Is your feature request related to a problem? Please describe.** My [CLI tool](https://github.com/mas-cli/mas) is primarily distributed via [Homebrew Core](https://github.com/homebrew/homebrew-core), but it isn't recognized as being published as a package. **Describe the solution you'd like** Homebrew Core formulae recognized as packages. **Describe alternatives you've considered** None. **Additional context** The following could also be supported as package managers, but I didn't want to open too many issues at once: - [Homebrew Cask](https://github.com/homebrew/homebrew-cask) - Custom Homebrew tap formulae/casks - [MacPorts](https://www.macports.org) - [nixpkgs](https://github.com/nixos/nixpkgs)
