message: docs: add aspell to mac dependencies to fix check format script
diff: @@ -50,7 +50,7 @@ for how to update or override dependencies.
  On macOS, you'll need to install several dependencies. This can be accomplished via [Homebrew](https://brew.sh/):
  ```
  - brew install coreutils wget cmake libtool go bazel automake ninja llvm@7 autoconf
  + brew install coreutils wget cmake libtool go bazel automake ninja llvm@7 autoconf aspell
  ```
  _notes_: `coreutils` is used for `realpath`, `gmd5sum` and `gsha256sum`; `llvm@7` is used for `clang-format`
