Sources without a URL scheme get directed to an internal reference

[AetherUnbound]

Description

Originally reported by @xolotl on the Make WP Slack.

Presently, the iNaturalist source URL on the production sources page is: https://search-production.openverse.engineering/inaturalist.org

It looks like this is because the API's v1/images/stats response is returning the source_url field without a scheme (e.g. inatrualist.org vs https://inaturalist.org):

We could ensure the scheme is added on the frontend, or perhaps we may even want to change this to a URLField instead of just a text field to ensure a scheme is applied. I'm happy to move the issue if the latter is preferred!

Additional context

I plan on fixing this value in the API's Django admin shortly after filing this issue, so it will (hopefully) not be reproducible in production.

Thanks for sharing this. My feelings are mixed on how to fix it. I suppose I regard it as a typo; perhaps this could just be solved in documentation. I'm not sure we actually have instructions for the steps to manually add and enable a new source in Openverse, which would be an excellent place for this.

I like the idea of converting the text field to a URL field as that would validate it and be a more certain solution than adding documentation. Is there an argument against it, @zackkrida?

@obulat that sounds good to me, no argument against it!
