Bump MAX_VALUES_CHOICE_PARAM from 1000 to 1001 (#5116)

Summary:

Bump MAX_VALUES_CHOICE_PARAM from 1000 to 1001 in Ax ChoiceParameter to fix GitHub issue facebook/Ax #5108.

Users commonly want to split [0, 1] in 0.001 steps, yielding 1001 elements. The previous limit of 1000 blocked this natural use case. Updated the constant in parameter.py and adjusted 3 test values in test_parameter.py to match the new limit.
