/**
 * Google Analytics Component can be used for analytics purposes. This supports GA4 and the older version. 
 * Id will be picked from Amp config of BOLD. `Settings > Configure > AMP > GA tracking id`.
 * 
 * GA4 config will be picked up from `featureConfig`
 * Example: 
 * ...
 * ampRoutes(app, {
 *  featureConfig: {
 *    analytics: {
        googleAnalytics: { id: "G-XXXXXXXX" }
     }
 *  }
 * })
 * ...
