Fixes Youtubes stupid update idea to allow only 3 videos to load in each grid.
Youtube thinks they did a smart move once again today, forcing people to scroll 10 times more due to a stupid Grid update allowing only 3 videos to be loaded in each grid now.
This script will fix this "smart" choice, bringing back the 5-grid layout (or more if you want to)

You might get some minimal bigger space in between some videos
