feat(react-native-google-signin ): added to config-plugin

[heryTz]

Why

react-native-google-signin is not compatible with Prebuild. This plugin allows you to configure react-native-google-signin using Prebuild.

How

I take a look at the other Expo Config Plugins in this repo and copying their implementation.

Test Plan

I tested it locally

1. Install react-native-google-signin
2. Add configuration

   {
   "expo": {
   "plugins": [
     [
       "@config-plugins/react-native-google-signin",
       {
         "serverClientId": "my_serverClientId",
         "iosClientId": "my_iosClientId",
         "iosUrlScheme": "my_iosUrlScheme"
       }
     ]
   ]
   }
   }

3. Check Info.plist: ios/[project_id]/Info.plist

   
   ...

CFBundleURLTypes

<array>

  ...

  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>my_iosUrlScheme</string>
    </array>
  </dict>
</array>

...

GIDClientID my_iosClientId

...

5. Check strings.xml: `android/app/src/main/res/values/strings.xml`

... my_serverClientId

7. Run `npx expo prebuild --clean`
