Don't call the C function random_beta() with both parameters `a` and `b` set to 0. In the case where this would occur, we know that the remaining values in the random vector being generated must be 0, so can break out of the loop early. After this change, when alpha is all zero, the random variates will also be all zero. Closes numpygh-24210.

I updated the code so now, instead of generating an error, all zeros are returned when |
