Describe the bug

When using the VSCodeRadioGroup component, I noticed that the following code resulted in a Typescript error

<VSCodeRadioGroup orientation="vertical">
    <VSCodeRadio value="apple">Apple</VSCodeRadio>
    <VSCodeRadio value="banana">Banana</VSCodeRadio>
    <VSCodeRadio value="orange">Orange</VSCodeRadio>
  </VSCodeRadioGroup>

Type '"vertical"' is not assignable to type 'Orientation | undefined'.ts(2322)

While I was able to resolve this by importing the RadioGroupOrientation enum from the package, it struck me as odd that the string vertical or horizontal didn't satisfy the orientation prop. Particularly considering the definition of the enum itself 👇

import { RadioGroupOrientation } from "@vscode/webview-ui-toolkit";
console.log(RadioGroupOrientation) // {horizontal: "horizontal", vertical: "vertical"}

As a React developer, I would expect both values – "vertical" and RadioGroupOrientation.vertical – to function correctly here.
