Add "version" and "path" output variables for task

This release adds new output variables: path and version:
They can be consumed in next steps:

- uses: maxim-lobanov/setup-xcode@v1
  name: Setup Xcode
  id: setup-xcode
  with:
    xcode-version: latest-stable
- name: Print output variables
  run: |
      echo "Version: ${{ steps.setup-xcode.outputs.version }}"
      echo "Path: ${{ steps.setup-xcode.outputs.path }}"

Also, bumping dependencies to latest versions and improve code quality with prettier.
