Bump notify to 5.0.0-pre.11 (#2564)

# Objective

notify 5.0.0-pre.11 breaks the interface again, but apparently in a way that's similar to how it used to be

## Solution

Bump `bevy_asset` dependency on notify to `5.0.0-pre.11` and fix the errors that crop up.

It looks like `pre.11` was mentioned in #2528 by @mockersf but there's no mention of why `pre.10` was chosen ultimately.
