TEST: enabled third_party cupy tests for distributions check

[samir-nasibli]

Description:

• fixed tests for dirichlet, beta distributions

• removed 20 test cases form list

TODO

• tests/third_party/cupy/random_tests/test_distributions.py::TestDistributionsBeta_param_0_{a_shape=(), b_shape=(), shape=(4, 3, 2)}::test_beta

the same comment as is on #342

2. fails when calls dpnp on backend (CPU):
