Fix: Prevents 414 request-uri too long for import_articles_by_title by using a POST request

[empty-codes]

What this PR does

Fixes 414 request-uri too long for import_articles_by_title by using a POST request instead of a GET request:

• Adds kn.wikipedia.org to list of stubbed wiki validations
• Adds meta method in wiki_api to prevent:

      Failure/Error:
       def query(query_parameters = {}, http_method: :get)
         mediawiki('query', query_parameters.merge(http_method: http_method))

     ArgumentError:
       unknown keyword: :meta
     # ./lib/wiki_api.rb:23:in `query'
     # ./app/models/wiki.rb:188:in `ensure_wiki_exists'

The former code site_info = WikiApi.new(self).query(meta: :siteinfo) in wiki.rb's ensure_wiki_exists method worked because the query method is a general entry point for all API requests and the mediawiki gem automatically processes meta requests since it is a valid method. My change to wiki_api's query method however bypasses the gem's automatic routing of meta: :siteinfo causing the error.

The solution was implementing a meta method in the WikiApi class that directly calls the meta method from the mediawiki-api gem.

• Adds a test that confirms 414 request-uri too long no longer occurs and a new vcr-cassette some_article_titles.yml

This looks great. I can merge it if the tests pass.

I just checked and it's the same usual 429 error that occurs so it wasn't caused by this. I guess sentry is notifying because it's the first occurence after I changed query
