Merge pull request #2315 from keep-network/add-jq-to-osx-setup

Add jq to the macos Setup Script

The manual setup doc details that "If you are not on macOS or you don’t have
Homebrew, you need to install:", and then lists jq, but the macos-setup.sh script
doesn't install jq for you.

I also confirmed that jq is indeed necessary for the project via bricking by not
having it XD

This PR adds a brew line to install it similar to how the rest of the dependencies are
installed!
