Incorrect method for customizing camera inputs

[saaratrix]

Hi I was implementing custom inputs for a camera and on this page:
https://doc.babylonjs.com/how_to/customizing_camera_inputs

It's mentioning this method several times: getTypeName

But it should actually be getClassName

This is the actual interface:

I made a PR for the documentation changes and I noticed that in the camera inputs manager there is a typo (intput) :):

This is changed and fixed in the new documentation pages, coming with the 4.2 release. Changes will not be visible until then.
