Add bevy_render::texture::ImageSettings to prelude (#5566)

# Objective

In Bevy 0.8, the default filter mode was changed to linear (#4465). I believe this is a sensible default, but it's also very common to want to use point filtering (e.g. for pixel art games). 

## Solution

I am proposing including `bevy_render::texture::ImageSettings` in the Bevy prelude so it is more ergonomic to change the filtering in such cases.
