In the Cartesian coordinate system $xOy$, with the origin $O$ as the pole and the positive half-axis of $x$ as the polar axis, the polar equation of curve $C$ is $\rho=2\sin \theta$, $\theta\in[0,2\pi)$.  
(Ⅰ) Find the Cartesian equation of curve $C$;  
(Ⅱ) Find a point $D$ on curve $C$ such that its distance to the line $l$: $\begin{cases} x= \sqrt {3}t+ \sqrt {3} \\ y=-3t+2\end{cases}$ (where $t$ is a parameter, $t\in\mathbb{R}$) is the shortest, and determine the Cartesian coordinates of point $D$.
