Add React ^17.0.0 as peer dependency to support Gatsby v3 and "gatsby-plugin-netlify-cms": "^5.0.0" #5111
Description
Describe the bug
With the release of Gatsby v3 and "gatsby-plugin-netlify-cms": "^5.0.0" the move to React 17 has been made. netlify-cms-app however requires React 16 as peer dependency. This is a request to add React 17.
To Reproduce
- Include
gatsby-plugin-netlify-cms": "^5.0.0",and"netlify-cms-app": "^2.14.29"to yourpackage.json - Make sure you are on npm >=7.0 as this uses the new peer dependency resolution
- Run
npm install

Current workaround
Use the npm --legacy-peer-deps flag and install by npm install --legacy-peer-deps
