Refactor macdeploycheck installation and update Brewfile tap path

This commit modifies the `macdeploycheck` formula to install the script directly from the tapped repository instead of using a local file URL. Additionally, the `Brewfile` is updated to use the directory of the Brewfile for the tap path, ensuring compatibility when running `brew bundle` from different locations. The `install_brew_deps.sh` script is also enhanced to provide more detailed error messages when missing formulae are detected.

-One or more binaries in your .app link to a Homebrew (or MacPorts) path.
-That usually means the bundle is not self-contained and will fail on other machines,
-or will fail notarization/codesigning validation.
-
-Fix: re-run your deploy step (e.g. macdeployqt) so frameworks/dylibs are bundled and
-their install names are rewritten to @rpath/@loader_path.
