Wiki: Texture packing updated (#10851)

* Wiki: Remove texture atlas info from the Introduction, minor formatting changes

* Wiki: Add texture atlas info back in under Images-and-Audio, expanded (external tools, settings, encoding warning).

* On second thought...

* Double-check wording for 'game.png is no longer a special boy', ensure game atlas is merged into textureRegions only once

-### More on Images and the texture atlas
-
-When running on Desktop, images are combined on game startup into a large `game.png` file with a corresponding `.atlas` file.
-
-This means that if you're developing your mod on an Android version of Unciv (not recommended!) you won't be able to generate these images files - you can ask someone in the Discord server to help you out
-
-For your players, the individual images aren't important - only the combined images actually register to the game, so you need to include them in your repository and keep them up to date.
-
-Actually omitting the original images would work for these uses, but we still recommend including them, so developers running from source can access them.
-
-#### Extremely image-heavy mods
-
-If your mod has lots of images (or large ones), the textures might 'spill' into additional texture ".png" files - 2048x2048 is the limit for a single texture pack.
-
-This is not good for performance, which is why the base game controls which kinds of images go together into one texture(+atlas).
-
-This works for mods, too: Create not only one Images folder, but several, the additional ones named "Images.xyz", where xyz will become the filename of the additional texture file (So don't use both Images and Images.game - those will clash). Look at the Unciv base game to get a better idea how that works.
-
-To minimize texture swaps, try to group them by the situation where in the game they are needed. You can distibute by folder, but having the same subfolders under several "Images.xyz" and distributing the images between them will also work.
