Resets the element's visual validity indication.
Many elements have a visual cue that indicates whether they are valid or not. For example, a text input that usually has a black outline might have a red outline when its value is not valid.
The resetValidityIndication() function resets the validity indication
of an element to show the element as valid. The actual validity state of
the element is not affected. If the element was invalid, it remains
invalid. The validity indication shows the element as valid until
the element's validity is checked when the value of the element
changes either by user interaction or programmatically. At that point,
the element's validity indication shows the element as invalid if
its value is not valid.
