rename parameters in `gui.js`

[nikochiko]

The current signature is very misleading because its src=... argument does not take a javascript URL, but simply raw javascript code.

def js(src: str, **kwargs):
    ...

ExecJs only creates a Function out of it (using the raw body as the function's body, inside useEffect).

gooey-gui/app/renderer.tsx

Lines 456 to 471 in d6af022

	function ExecJs({ src, args }: { args: any; src: any }) {
	const submit = useSubmit();
	args.gooeyRefresh = () => {
	const elem = document.getElementById("gooey-form");
	if (elem) submit(elem as HTMLFormElement, ...arguments);
	};
	useEffect(() => {
	// eslint-disable-next-line no-new-func
	const fn = new Function(...Object.keys(args), src);
	fn(...Object.values(args));
	}, [src, args]);
	return null;
	}

let f = new Function("a", "b", "console.log(a);")

will be same as

let f = (a, b) => { console.log(a); }
