Remove the remainder of overlapping notes from songs

Title. These only exist on the Opponent's side so they don't affect the player's experience, but I think it'd be nice to remove them anyway. Notes removed can be seen below (via the feature implemented by PR Funkin/3574).

My favorite kind of PR

Is there a way to apply these fixes by removing lines from the original files? That would make the diffs easier to read!

[NotHyper-474]

As much as I'd like to, the chart editor likes to reformat and reorder everything. And VSCode's diff viewer is taking forever to load so I can't even try to fix it manually.

Edit: I think I got it now, currently managed to reduce the diffs on 2hot-chart by a LOT.
Edit 2: Did the same with Fresh Pico Easy. It was easier than I expected since the chart editor only reordered the difficulties, so I just had to reorder them back.

Alright, finally managed to undo the "mess" the chart editor did. Diffs should be way more readable now.
Now the large label is incorrect lol

Thanks for going through all that!

Also really awesome application of your overlapping note viewer :)
