Enable request authentication

There will be a change in the rate-limits of the Wikipedia API in April. The rate-limits are different for authenticated and non-authenticated requests as well as those with and without user-agent: https://www.mediawiki.org/wiki/Wikimedia_APIs/Rate_limits

It would be nice to support authentication on the API to not be troubled with low rate-limits.

As of 2026-07-25 (s. image below) there is not difference for bots and new users in terms of requests/min. Only users with lot of edits will benefit from this. IMHO decreases this rate limit the necessity of authentication.
