 This release breaks radio buttons, which is something that needed to happen to solve a longstanding accessibility issue where screen readers announced an incorrect number of radios, e.g. "1 of 1" instead of "1 of 3." Many attempts to solve this without breaking the existing API were made, but none worked across the board. The new implementation upgrades `<sl-radio-group>` to serve as the "form control" while `<sl-radio>` and `<sl-radio-button>` serve as options within the form control.
