Radio: SVG exposed as image with accessible name

[sirrah-tam]

Expected behavior
SVG used as the visual for the radio button hidden as decorative since the actual radio input is exposed to assistive tech (AT).

Actual behavior
SVG has been given the aria-label attribute with the value of "radio", this adds to the verbosity of the component for AT users navigating a page with multiple radio buttons.

Steps to reproduce the issue

1. Inspect the radio button
2. Locate the SVG used to visually represent the control
3. Verify the aria-label attribute used.
