Drop the patch to disable initialization of URLQueryStrippingListService
For #40788 (closed), I added a check to disable the initialization of URLQueryStrippingListService
when not needed (with e8921475).
I also opened an upstream bug, which has been dealt with.
The resolution isn't trivial to cherry-pick, so we could keep my patch for 12.5, and then drop it when switching to ESR 115.
