Update some images in the docs

[kna27]

Some of the images on the kOS docs are quite old and outdated, as the GUIs of both kOS and KSP has changed since then. I remade all of the images on this quickstart tutorial page in 1.11.2, and they are all the exact same resolution and size as the previous ones. I also changed some other pictures that have the most outdated GUIs. I feel that the images that haven't had too many changes with game and kOS updates do not really require updates, as it is still easy to understand what the images are portraying in newer versions of kOS and KSP. Fixes #2952

Thanks for doing this. It's a thing I'd always been meaning to get around to but never did.

(By the way, in the future it's a good idea for you to make a new branch on your fork where you do the pull request from rather than having them just be from your develop branch. Having them from your develop branch worked fine here only because you didn't have anything else you were working on in kOS. If you work on more than one change, having them in separate branches becomes important.)
