Remove the npm_presenter_queries_tuning feature flag
🔧 Context
In #243780 (comment 649798873), we noticed that the npm presenter had a n+1 issue. It was looping on a set of npm packages and for each package it would load the dependencies object.
That presenter is used mainly by two "metadata" API endpoints. Those endpoints are used by npm commands such as $ npm install or $ npm view.
Being a heavily used package registry on gitlab.com, the n+1 removal is gated behind a feature flag.
The incremental rollout went well and we had the expected results: a reduction in SQL queries count.
It is now time to remove this feature flag.
