fix: Forward data-* attributes to inner button element in copy-to-clipboard

attributes being on or near the click target cannot associate click events with the analytics metadata,
resulting in empty values in dashboards.

Unlike components like Button (where the root element IS the interactive <button>), CopyToClipboard
has a passive <span> root with the click target buried inside a Popover:
