HowTo_Tile_Sprites.html has two corrupted PNGs #65
Description
On the How To Tile Sprites doc there are some PNGs that have been corrupted and are displaying as broken image links:
https://docs.monogame.net/articles/getting_to_know/howto/graphics/HowTo_Tile_Sprites.html
While I could guess at what MonoGame.png and a tiled version would look like, I assume somebody might have the originals, and be able to fix it. If not I can make an attempt to re-create them and submit a PR!
Screenshot as well:
