Browse source 
Signed-off-by: Lena Milizé <me@lvmn.org>

# Objective

Fixes #6277.

## Solution

Adds `# Panics` section to [`fn insert_non_send_resource`](http://dev-docs.bevyengine.org/bevy/ecs/world/struct.World.html#method.insert_non_send_resource) documentation, which explains that it panics when called from thread other than main thread.
