Feature: Automatically check APIs for new languages

[bittlingmayer]

Problem:
We have to manually check documentation for new languages. And often the documentation, is behind the APIs.

Request:
Write a script to ping each API and update apis.json. Then we could re-run the script, and then see the changes.

Additional context:

• Most machine translation APIs have a path like /languages to get this info. Usually it's free, but it still requires an API key.
• The challenge here is that they come in many different formats, and we'd need API keys for each one.
• The API keys should not be in the code.
