Add blendMode and opacity properties for SectionNode

In the Figma editor, you can change the blend mode and opacity for Sections. But blendMode and opacity properties is missing in both Plugin API and REST API, so it is not possible to read/write it.

Please add these properties to the SectionNode object.
