/**
 * Adds a prop to a JSXElement.
 *
 * Returns a `StringableASTNode<JSXElement>` so that callers can immediately
 * `.toString()` the result inside an ESLint fixer, and so the result can be
 * composed with other node helpers without forcing callers to supply a
 * synthetic `loc`/`range`.
 *

 * @example
 * ```
 *  const boxNode = jsxElement({ ...node })
 *  console.log(boxNode.toString()) // --> "<Box></Box>"
 *
 *  const boxNodeWithProp = insertJSXAttribute(node, 'display', 'block')
 *  console.log(boxNodeWithProp.toString()) // --> "<Box display='block'></Box>"
 * ```
