Gets the page's title.
The title is an important factor that lets search engines determine the topic of a page.
Note:
You should always invoke the wixSeoFrontend.title getter outside of the onReady() event handler to
ensure receiving the proper response.
import wixSeoFrontend from "wix-seo-frontend";
// ...
let title = wixSeoFrontend.title; // "Page Title"
