Add pixelated Bevy to assets

[alice-i-cecile]

@dtcristo, the author of bevy_pixels created the awesome little pixeled Bevy shown below.

To avoid confusion with the official project, they've offered to it to Bevy to use:

Feel free to use it for whatever official purposes you want. I created it using https://www.pixilart.com/

As we progress on #1856, it would be valuable to have test assets of this sort, and this is both small and cute.
I've attached the image and .pixil file below.

Really nice! It could even be used in a loading screen before a pixel game start menu.

I noticed that the colors weren't in the order of the official logo. Here is an edit I made, just in case people prefer it.

Hi, I would like to help on this. But I don't really understand what needs to be done. Is it writing unit tests on loading assets or use this as the default loading screen?

@Ian-Yy this just needs to be added to added to the assets folder with an appropriate license listed, and then used in a pixel_perfect example in the 2D folder. That example should demonstrate how to set the filtering mode to an appropriate setting for pixel art, and move the pixelated logo around a bit to verify that everything looks okay.

Hi @alice-i-cecile. I have created the PR. I am not sure what I should do with the appropriate license. And for pixel_perfect, I am just using the filter mode nearest. Not sure if this is okay, but I have check that the image doesn't stretch and distorted when moving. Please let me know if this is right or there's a different filter mode or direction to go. And in the docs, I keep seeing ImageSettings but in the 9.0-dev, it's ImagePlugin and implemented using add_plugin instead of insert_resource which make me so confuse.

I'll reply on the PR :)
