* Restructure query-languages docs files for clarity (#124797) In a few previous PR's we restructured the ES|QL docs to make it possible to generate them dynamically. This PR just moves a few files around to make the query languages docs easier to work with, and a little more organized like the ES|QL docs. A bit part of this was setting up redirects to the new locations, so other repo's could correctly link to the elasticsearch docs. * After running tests, we revert a few features * Fix build.gradle and improved some generating code * After running tests * Update x-pack/plugin/esql/build.gradle
