patch

Adds "yarn dev" command to simplify local development.

To add the command to an existing application, first add it to the scripts section of your monorepo root package.json like so:

 "scripts": {
+    "dev": "concurrently \"yarn start\" \"yarn start-backend\"",
     "start": "yarn workspace app start",
     "start-backend": "yarn workspace backend start",

And then add the concurrently package to your monorepo, like so:

yarn add concurrently@6.0.0 --dev -W

Notes:

• This needs to be done to the monorepo root, not your frontend or backend package.
• The --dev -W will add it only to devDependencies, and force it to the monorepo main root.

You can then run yarn dev which will start both the Backstage frontend and backend in a single window.
