Missing legend_size on datadog_dashboard

The new datadog_dashboard resource does not include legend_size on widgets defined with timeseries_definition, like the datadog_screenboard resource used to include.

Affected Resource(s)

datadog_dashboard

Expected Behavior

There should be a way to set legend_size

Actual Behavior

There is no way to set legend size

I can see the property is in the code, may not be in the documentation yet. Try passing in the legend_size property, it's a type string.

I had tried that first, actually, assuming the resource was cloned from the previous screenboard resource. Unfortunately it does not work, as subsequent plans still show legend_size being added.

Likely the same issue as #329.
