74b944af - gh-156635: Fix the exceptions in the xml.dom documentation (GH-156636)

gh-156635: Fix the exceptions in the xml.dom documentation (GH-156636) Node.insertBefore(), Node.removeChild() and Node.replaceChild() raise NotFoundErr, not ValueError. Element.removeAttribute() and Element.removeAttributeNS() raise NotFoundErr if there is no matching attribute, which contradicts the DOM, so this is documented as a deviation in the minidom documentation.
