Google OAuth + Netlify deployment

[cboiteux2765]

Working hosted UI sign-in and a short setup note (callback URLs, client ID, env vars)

[cboiteux2765]

I'm currently working on testing the Cognito and Google OAuth integration with localhost, currently not working but probably do to a setup issue in Amazon Cognito or the Google Cloud Console. I am also gonna add Next.js routes to start the localhost:3000 server so that the test URL will work for OAuth

So now the localhost page sign in to google does pop up the google sign in and I signed in with the coderhub account but I'm getting an {"error":"invalid_client","error_description":"invalid_client_secret"} but need to add the client secret in the .env.local for Next.js server for testing auth
