One issue that I mentioned in FunkinCrew/Funkin/issues/3105

Description

1. Improved almost all offsets for some characters animations (except for those using spritemaps).
2. Changed the order of some animations in the .json files to make it a little more intuitive. It follows this order:
   • Idle/dance
   • Sing
   • Sing miss
   • Sing-alts (alt, censor, etc.)
   • Hey, cheer
   • Other animations during songs
   • Death animations
   • Cutscene animations
3. Removed "singDOWN-Hold" from dad.json, as it is used for his eye animation, but in "singDOWN" his eyes are not open.
4. Fixed "SingRIGHT" animations in momCar.json and its .xml.
5. "SingLEFT" and "SingRIGHT" animations in monster.json and monster-christmas.json have been returned to how they appear in their .xml.

For some of this characters (like Tankman and Darnell) I also used the foot that was pointing towards the camera in the idle animation as a reference, but in many other characters (like Daaddy Dearest) I changed to use the other depending on the animation
If you notice any errors or changes you don't like, let me know so I can change them.

I don't know how I just messed up the momCar.xml diff, sorry
