[PRQ#57497] Deletion Request for ruby-mediawiki_api

MarsSeed [1] filed a deletion request for ruby-mediawiki_api [2]: Not compatible with current Ruby 3+ libs and ruby-faraday from repo. This package never worked since submission. Not useful to keep. See also deletion request of its sole consumer that was also always broken: catimporter (PRQ#57496).
