Tiled Gallery block: Open Link to Media File Opens Only that Image

[tmmbecker]

With the old Tiled Galleries, linking to a Media file would load the images from the CDN in a carousel, including an option to close the carousel to return to the post.

The Tiled Gallery block opens only the selected image in a lightbox-type window with no clear way to get back to my post:

Steps to Replicate:

1. Create a Tiled Gallery.
2. Select Media File as the Link to.
3. Save the post and view it.
4. Click one of the images in the tiled gallery.

We probably need to update something in Carousel JS in Jetpack, similarly like was done for Core Gallery: Automattic/jetpack#10646

If there is a core gallery and a tiled gallery block, the tiled gallery block is annotated incorrectly and the carousel doesn't work.

These will need updating:
