Make Donut metric optional

[natvilla]

Provide a general summary of the feature here

In order to make a small multiple, request that the center metric text be optionally rendered. Would be good if maintains accessibility. One possibility is to render it to the side/above/below. See example.
But may also be good to leave metric off altogether if there is a need.

🤔 Expected Behavior?

Have metric & metricLabel be optional props?
