Landing pages for sources without a search query

[zackkrida]

Problem

Previously, Openverse allowed users to go to a queryless search results page to view images from the different sources. An example url would be something like:

https://wordpress.org/openverse/search/image/?source=rawpixel

Notice the lack of the search (q=dog&) parameter.

Description

Restoring this feature would be nice, but it would also be nice to make it more robust. It could be a really nice way to showcase the sources with more detail. Some potential ideas:

• Add a header to the search results that shows the name, a textual description, and logo of the source, along with how many pieces of various media they have in each media type.
• Have an external link to the source
• Link to the source's content moderation policy and other relevant documents to Openverse.

This would require us to maintain more metadata for providers in the API.

Alternatives

Do nothing, and simply merge WordPress/openverse-frontend#1008.
