Edited all Arc 4 completed pages, minorly (Patreon)

I -just- now realized that I had not changed the lower left info of each of Arc 4's pages, so they all still said "Arc 3: Part 3". If you are one to save stuff on your drives, update them with the new versions. I just edited each post and re-uploaded the files to have correct lower left text info:

Edited both the image post itself as well as the full version in the attachment for each. Sorry about that small goof!
