update examples to three v127

[kayhhh]

i broke the examples in my last PR 😬 woops

fixed by updating the examples to three version 0.127.0, which supports the new syntax changes

important to note that in any three version beyond 0.127.0, the examples are broken. this is because starting in 0.128.0 certain three components like Object3D are ES6 classes (https://github.com/mrdoob/three.js/wiki/Migration-Guide#r127--r128) and its causing errors.
