Use /languages endpoint

[caugner]

DeepL now provides an API endpoint to list the supported languages: https://www.deepl.com/docs-api/other-functions/listing-supported-languages

Using this endpoint avoids having to adapt the library for every new language.

Note: With PT-BR and PT-PT, DeepL now also supports two variations: https://www.deepl.com/en/blog/20200402.html

Hello @caugner ,

so can I add them just as any other language? I guess: yes?

Yes, for now you can add them like any other languages (i.e. all uppercase, "PT" is still supported and equivalent to PT-PT).

For the future it would be nice to retrieve the list of supported languages directly from their endpoint.

@chriskonnertz DeepL also supports Japanese (JA) and Chinese (ZH) since March.

Languages updated.

Decided not to use the language update and rather hard-code the list to avoid trouble.
