fix(SelectPanel): pass anchorId to AnchoredOverlay

[francinelucca]

Closes https://github.com/github/accessibility-audits/issues/10036

Changelog

A FormControl's Label is not currently being associated with the SelectPanel control due to the id not being passed to the AnchoredOverlay. This PR explicitly passes the ID provided to the SelectPanel to the AnchoredOverlay's menu.

Changed

• pass SelectPanel's id as AnchoredOverlay's anchorId
