Skip route group immutable test (sonic-net#3393)

What I did
Skip VS test dash/test_dash_route_group.py::test_bound_route_group_immutable

Why I did it
This test causes orchagent to crash since the VS SAI has not been updated to include implicit deletion of high-volume DASH objects (https://github.com/sonic-net/SONiC/blob/master/doc/dash/dash-sonic-hld.md#18-implicit-deletion-of-sai-objects)
