Fix access conflicts for resources (#14635)

# Objective

- I made a mistake when fixing the merge conflicts here:
https://github.com/bevyengine/bevy/pull/14579#discussion_r1705377452

It wasn't caught because there's no easy way to trigger access conflicts
with resources without triggering them with components first.
