Remove aria-required attribute from semantic element `input`

[jdufresne]

Per the MDN docs, the aria-required attribute is only necessary on non-semantic elements. The input element is a semantic element and so aria-required is not necessary -- just required is sufficient and achieves the same result. An example of a non-semantic element is div which is not used by the project.
