DOC: Missing positional arguments in Wikidata Langchain documentation. Path: /v0.2/docs/integrations/tools/wikidata/

Checklist

• [X] I added a very descriptive title to this issue.
• [X] I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

The current documentation does not cover the positional arguments required by the WikidataAPIWrapper. It needs the arguments wikidata_mw and wikidata_rest.

Link to faulty documentation page: https://python.langchain.com/v0.2/docs/integrations/tools/wikidata/

Idea or request for content:

Please update the code with the required arguments, and please explain from where we can get it. If needed, I can work on it as well. Thanks!

I tried with # type: ignore the query runs but fails after

also i think those docs are wrong that it's blah.run it should be .invoke as the main tool calling interface.

tho i still see run in master here: https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/utilities/wikidata.py

what a mess. every time i use langchain i regret it and just go back to the working underlying libs it's just easier.

if you're gonna add obfuscation wrappers, at least don't make broken wrappers AND broken docs.
