Make IDLE ANIMATIONS to all mobs and WALKING ANIMATIONS more vanilla-style

Camel (Husk), Sniffer, Armardillo are still a bit too realistic and don’t fit with Minecraft in walking animation. Typically, Minecraft mobs rotate their legs in a pendulum-like motion, with a fixed, stationary point serving as the axis around which the entire leg rotates. The idle animation is acceptable because it remains very vanilla, but the walking animation - which involves lifting the legs - loses some of its vanilla feel. However, for some new mobs like the Warden or the Copper Golem, walking animation makes perfect sense and still maintains a vanilla aesthetic. The Frog is an exception because if its current walking animation were removed, its movement would look very odd. Therefore, I propose adding idle animations to all mobs that don’t currently have them, while making the walking animations for the Camel (Husk), Sniffer and Armadillo feel more vanilla.
