Missing padding from cartesian chart item labels in embedding SDK

[heypoom]

Chart padding was removed due to the isEmbeddingSdk check in getChartPadding, which makes it so that there is no padding between cartesian chart item labels and the dashboard card container.

const getChartPadding = ({
  isEmbeddingSdk,
  isQueryBuilder,
}: CartesianChartRootProps) => {
  if (isEmbeddingSdk) {
    return "0rem";
  }
  if (isQueryBuilder) {
    return "1rem 1rem 1rem 2rem";
  }

  return "0.5rem 1rem";
};
