Re-align folder names for chapter images to make sure they match up with chapter's filename

[AndrewRathbun]

i.e., chapter5.txt has references to ![](Ch8/chapter8001.jpg), because it was likely the 8th chapter that was promised, but it was the 5th chapter finished, so the numbers never got "re-aligned", for lack of a better word.

And now, chapter4.txt has references to Ch5\1.png, so I can't rename the folder currently assigned to chapter5.txt to Ch5 because chapter4.txt is currently pointing to Ch5 😆 it's a bit of a mess, but right now "it works", it's just not pretty, but there's a reason for it being this way, but that doesn't mean it needs to stay this way.

The way the chapters are named now (chapter1, chapter2, etc) should align with the resources\ChX folder name, with preference for using the chapter's filename as the guiding light for what the resources folder should be named, aka let's not rename chapter manuscripts, just rename folders where the images currently reside, then replace the references within each chapter. This keeps the order of the book unchanged, whereas if we keep the names of the folders holding the images, then we're reshuffling the order of the book, which doesn't seem ideal.
