Typescript declaration for mathfieldelement needs declare module, not declare global, in React 19

[dkilfoyle]

In documentation https://mathlive.io/mathfield/guides/react/#using-a-mathfield-with-react-and-typescript

For React 19 need to replace declare global {...} with

declare module "react/jsx-runtime" {
  namespace JSX {
    interface IntrinsicElements {
      "math-field": DetailedHTMLProps<HTMLAttributes<MathfieldElement>, MathfieldElement>;
    }
  }
}

export {};
