[PRQ#48653] Deletion Request for qtcreator-plugin-icontheme-git

MarsSeed [1] filed a deletion request for qtcreator-plugin-icontheme- git [2]: Cleanup of long-broken, long-abandoned, unused Qt Creator plugins that still depend on the obsolete 'qtcreator-src' package instead of the correct 'qtcreator-devel', available in extra repo.
