For Camera2D, change the zoom property.
For 3D Camera, change fov for Perspective projection or size for Orthogonal projection.

There's InputEventMagnifyGesture with a factor property. I guess you can use it like this:

func _input(event):
  if event is InputEventMagnifyGesture:
    camera.zoom *= event.factor

Haven't tested it yet but this should get you started.
