[PIPE2D-908] Fix test breakage from PIPE2D-871

Thu, 30 Sep 2021 14:47:09 +0000

Following the merge of ~~PIPE2D-871~~, drp_stella fails the integration test:

_____________________ EstimateRadialVelocityTestCase.test ______________________
[gw8] linux -- Python 3.7.2 /projects/HSC/PFS/stack/20190925/python/miniconda3-4.5.12/envs/lsst-scipipe/bin/python3.7

self = <test_estimateRadialVelocity.EstimateRadialVelocityTestCase testMethod=test>

   def setUp(self):
       self.estimateRadialVelocity = EstimateRadialVelocityTask(config=EstimateRadialVelocityConfig())
       # It may be fearsome to use default_rng()
       # because numpy is planning to change the default RNG again as of 2021-09-15.
       # We call PCG64 explicitly.
     self.np_random = np.random.Generator(np.random.PCG64(seed=0x789abcdef0123456))
E       AttributeError: module 'numpy.random' has no attribute 'Generator'

I believe this comes from using a newer version of numpy than the stack supports.
