Ender Dragon's left wing is rotated incorrectly

The Ender Dragon left wing uses different rotation when compared to right wing, this is because X and Z rotation on the left wing are rotated incorrectly, which is causing this issue.

Steps to reproduce:

• Method 1

1. Give yourself a Monster Spawner and a Ender Dragon spawn egg

2. Place the Monster Spawner, then right click it while holding a Ender Dragon spawn egg, due to MCPE-170175, the game will renders a fullsize Ender Dragon model on top of the Monster Spawner

3. Observe

• Method 2

1. Download attached world and import it, then open the world

2. Activate "Run Me" command blocks, it will summon and instantly kill the Dragon

3. Observe

Expected results:
Ender Dragon left wing has the same rotation as the right one.

Observed results:
Ender Dragon left wing are rotated way down than it should be.

Fix:
This can be fixed by replacing the "wing1" rotation in "animation.ender_dragon.wings_limbs_movement"

From this (Vanilla):

"rotation": [ "7.16 - Math.cos(variable.flap_time) * 11.46", 0.0, "(Math.sin(-variable.flap_time) + 0.125) * 45.84" ]

To this (Fixed):

"rotation": [ "-7.16 + Math.cos(variable.flap_time) * 11.46", 0.0, "-(Math.sin(variable.flap_time) + 0.125) * 45.84" ]
