There is no need to disable Python packages for Python versions that are
no longer in Nixpkgs.
This change was generated using the following script:

    pattern='^\s*disabled\s*=\s*pythonOlder\s*"3\.\([0-9]\|10\)"\s*;\s*$'
    for f in $(find -name '*.nix'); do
        grep -q "$pattern" "$f" || continue
        sed -i "/$pattern/d" "$f"
        if [ $(grep -c pythonOlder "$f") == 1 ]; then
            sed -i '/^\s*pythonOlder,\s*$/d' "$f"
        fi
        nixfmt "$f"
    done

Apprise supports desktop notifications on macOS (e.g., via `apprise -b "Hello World" "macosx://"`). This feature uses terminal-notifier under the hood. Unfortunately, the potential paths to terminal-notifier are hardcoded into apprise. Thus, nixpkgs's apprise does currently not support desktop notifications on macOS.

This PR adds the terminal-notifier dependency under macOS and patches the hardcoded paths to use nixpkgs's terminal-notifier.
