fix: Update api spec and generate code for MetricInsight;

[mat1th]

This is a manual update of the spec, because the spec is incorrect;

This PR fixes issues in Apple's API Spec:

• The referenceVersions in the spec from apple lists only a String but the real response is a array of Strings.
• The percentageBreakdown in the spec from apple lists only 1 object but the realresponse is an array of PercentageBreakdownItem.
