Fixes test for empty handling non-throw checks. They were copy-pasted with 100 as the insert expected. Should be 0

Reorders some changes in the slice recommendations. There are likely better layouts, and some things may present as problems, but this was the simplest layout I saw.

Merge remote-tracking branch 'upstream/1.21.x' into feat/handler-rework

Fixes typo in template package. It should have been `resources` but it wasn't properly plural like items and fluids are

Minor documentation changes
