Re-enable the queries cli test

* Requires that QL_PATH environment variable is set and points to a
  checkout of github/codeql
* Adds the `quiet` flag to the cli. When set, this flag will prevent
  some modal dialogs from disrupting the flow. Currently, we only ensure
  that the upgrades dialog is avoided.
* Update the main.yml workflow to checkout the codeql repo
