fix(Dialog): suppress missing Description warning when no description provided (#976)

Radix warns when DialogContent has no DialogDescription rendered.
Now renders a hidden RadixDialog.Description by default so the
warning is suppressed without requiring consumers to pass a
description prop or aria-describedby={undefined}.

+Suppress Radix `Missing Description` console warning when no `description` prop is provided to `Dialog.Content`. A hidden `RadixDialog.Description` is now rendered by default so Radix's accessibility check passes silently.
