Summary:
Several blog and sharing improvements are included in this update.
* A larger default preview image is used when a blog post or doc is shared on social media as recommended by [best practices](https://developers.facebook.com/docs/sharing/best-practices#images).
* Follow other Facebook Sharing best practices such as associating the site with a Facebook Page (React) and a Page Admin (121800083 is my fbid, and I am an admin for the React page).
* If the shared blog post contains a hero image, use it as a share preview image.
* Use actual doc content instead of generic site description when sharing docs.
* Update existing hero images to use the larger recommended size.
* Add titles to each author's byline.
* Add author's avatar to their byline.
* Add Twitter Card support.
* Link to individual blog posts from the title and hero image in the blog index.

Summary:
A couple changes people requested. None of the author links were doing anything, so now they link to Twitter profiles, and also the references to react-native-web have a standardized style w\ react-native-web-player.
