format: Configure Prettier for all workspaces (#650)

This PR adds:
* Add Prettier as a devDependency with global `.prettierrc.json` configuration
* Add `prettier` npm script for all workspaces:
  * `npm run prettier` in a specific workspace will only format the files in the workspace
  * `npm run prettier` in root directory will format the files in all workspaces
* Run Prettier on all workspaces to format all relevant files
