Localize Wikipedia link/description

[albullington]

This issue involves collaboration with the web team. If a user is viewing the app in a non-English locale (i.e. French), they should see the Wikipedia description and Wikipedia link in their given locale.

A few ways this could potentially happen:

• We could try to return different links and content via the API request on TaxonDetails (this might not be possible)
• We could expose an additional endpoint for the Wikipedia description via API v2 and make two separate API requests on TaxonDetails (this is similar to what we're doing in Rails on the web)
• We could create a separate endpoint for both the description and the Wikipedia link

• [ ] If I view https://www.inaturalist.org/taxa/71956-Aloe?locale=fi I see a Wikipedia description, but if I view that taxon in that locale (suomi) in the app, I don't see one
• [ ] The "Read More on Wikipedia" link on TaxonDetails always seems to link to en.wikipedia.org
