PolygonOutlineGeometry.fromPositions(options) does not pass the `vertexFormat` parameter

It's not possible to create a PolygonOutlineGeometry using `Cesium.PolygonOutlineGeometry.fromPositions({ vertexFormat, ...})` since it is not supported.
However, when looking at the code it is just a wrapper for instantiating `PolygonOutlineGeometry` directly. I would have expected the `fromPositions` method to include all the options that `PolygonOutlineGeometry` accepted.

https://cesium.com/learn/cesiumjs/ref-doc/PolygonOutlineGeometry.html?classFilter=outlinegeom#.fromPositions
https://github.com/CesiumGS/cesium/blob/1.88/Source/Core/PolygonOutlineGeometry.js#L534

`PolygonGeometry.fromPositions` does correctly pass the `vertexFormat`:
https://github.com/CesiumGS/cesium/blob/1.88/Source/Core/PolygonGeometry.js#L877

Start in Source/Core/PolygonOutlineGeometry.js around line 534 and compare its fromPositions implementation with PolygonGeometry.js around line 877. Done means PolygonOutlineGeometry.fromPositions accepts and passes vertexFormat consistently with PolygonGeometry.fromPositions.
