docs: remove `THREE.` prefix from several addon uses (#28105)

* docs: `THREE.KTX2Loader` -> `KTX2Loader`

We no longer use the prefix `THREE.` for addons

* docs: `THREE.GLTFLoader` -> `GLTFLoader`

We no longer use the prefix `THREE.` for addons

* docs: `THREE.OBJLoader` -> `OBJLoader`

We no longer use the prefix `THREE.` for addons

* docs: `THREE.DRACOLoader` -> `DRACOLoader`

We no longer use the prefix `THREE.` for addons
