Canvas scaling on the example pages breaks mouse click events

[cart]

In retrospect, this makes sense given that we're working around winit by scaling the canvas directly. I don't think we should revert canvas scaling, as it makes the examples visible on mobile / smaller screens and that feels worth it to me.

This seems like it would properly fix our problem, if merged:
rust-windowing/winit#2074

In the interim, we should consider "mitigating quality perception damage". Some ideas:

1. Disable canvas scaling for examples that care about absolute mouse position and go back to a fixed size canvas.
2. Flag examples that care about absolute mouse position and add a warning to their page (maybe with a link to this issue).
3. Just remove examples that care about absolute mouse position until we have a fix.

Closing as fixed, although we may need to redeploy.

to use bevyengine/bevy#4726 on the website we will need to update some things on this side

FWIW I was not able to reproduce this issue just now, using Brave 134.1.76.73 on Ubuntu 24.04.2 LTS
