Feat: Add google.ClassificationMetrics, google.RegressionMetrics, and…

… google.Forecasting Metrics (#1549)

* Add google.ClassificationMetrics, google.RegressionMetrics, and google.ForecastingMetrics Artifact types to metadata schema with unit tests.

* fix implicit false

* Fix typo

* Running nox -s blacken and nox -s lint

* fix typo in unit test
