Missing `amplify init` instructions in RN project setup

[tannerabread]

Describe the bug
In the project setup for React Native under the libraries tab, there is no mention about initializing an amplify project with amplify init. If a user follows the Project Setup guide and then tries to use a category, they will not have an Amplify project set up and will get errors about trying to add categories

To Reproduce
Steps to reproduce the behavior:

1. Go to https://docs.amplify.aws/lib/project-setup/create-application/q/platform/react-native/
2. Follow the instructions listed on the page
3. Navigate to any category's "Getting Started" page and try to add the category with amplify add *
4. See error shown below

Expected behavior
Project setup page tells you to initialize the Amplify project

Screenshots

Desktop (please complete the following information):

• OS: macOS
• Browser: chrome
• Version: 107.0.5304.87

Additional context
Should be similar but not identical to the setup for JavaScript under the Create a new Amplify backend heading but tailored to React Native
