Current behavior 😯

In v7 the CheckboxButtonGroup does not longer render the options label.

<CheckboxButtonGroup
  name="basic-checkbox"
  options={[
    {
      id: "1",
      label: <div>I am a div</div>,
    },
    {
      id: "2",
      label: "I am a string",
    },
  ]}
/>

Expected behavior 🤔

Since this breaking change was not mentioned in the somehow release notes, I am expecting this as a bug and that the options label getting rendered again to be also compatible with the MUI FormControlLabel label props
