OLED

## Additions:
+ Added a darker texture of the book (Subject to change, I'm not happy with this result)

## Improvements:
+ Improved UI of Gamemode Switcher (F3 + F4)
+ Improved recipe book non-craftable and craftable items frame color (Red/Green)
+ Changed the pack icon, as well as the typo.

## Other:
+ Updated for Minecraft 1.20.2 new folders (It was so painfull)

## Notes:
+ A new add-on resource pack for OLED is comming very soon, called "OLED+", it's basically made for mods compatibility, more info when I will release it!
+ OLED is now on a stable state, it's no longer in beta state, consider it as "finished", I will still do modifications and corrections if I need to!
