shapely.make_valid should be run on every shape after vectorization. It will fix the "polygons with holes"

Research direction
Start by reproducing the invalid polygon case from the linked polygons_test.ipynb, then trace the vectorization entry point in spatialdata. Check how vectorized shapes are returned and add coverage for polygons with holes. Done means every shape produced by vectorization has been passed through shapely.make_valid and the example no longer produces invalid shapes.
