InstancedBufferGeometry: Remove unused argument from super.toJSON()

[ycw]

Its base class .toJSON() takes no argument:

three.js/src/core/BufferGeometry.js

Lines 856 to 867 in 735d376

	toJSON() {
	const data = {
	metadata: {
	version: 4.5,
	type: 'BufferGeometry',
	generator: 'BufferGeometry.toJSON'
	}
	};
	// standard BufferGeometry serialization

Looking at the code: It seems InstancedBufferGeometry.clone() can be removed since BufferGeometry.clone() has the same implementation.
