The tags and categories count queries are failing on Rails 6.1 with `ERROR: column "topics.bumped_at" must appear in the GROUP BY clause or be used in an aggregate function`. The reason these queries didn't fail prior to 6.1 was because Active Record would automatically drop the `ORDER BY` clause from the queries when we called `count` on them. This behavior has been [changed](5812feffe3) in 6.1 so now Active Record only drops the `ORDER BY` clause if there is no `GROUP BY` clause. Our queries do have `GROUP BY` clauses, so we need to drop the `ORDER BY` clauses ourselves before we call `count` to make them work on 6.1.
After internal discussion, the team decided to rename this plugin to `discourse-docs`. No substantial changes made here aside from a settings migration.
