Test Failure after adding a case for setting graph.style.palette_flip = true

gistfile1.txt

// Set with:
graph {
	title = "Redis memory usage"
	viz = "timeseries"
	style {
		palette_flip = true
	}
}

//added matching step check:
resource.TestCheckResourceAttr("datadog_timeboard.acceptance_test", "graph.1.style.palette_flip", "true"),
