The API documentation of [[ https://docs.blender.org/api/current/bmesh.types.html?highlight=faces#bmesh.types.BMFaceSeq.new | bmesh.types.BMFaceSeq.new ]] indicates that the argument is only `BMVert`. But the correct one is sequence of `BMVert`. This patch fixes this mismatch. Contributed by @Nutti Differential Revision: https://developer.blender.org/D15668
