`assert_negative_support` function is being used inside the `StickBreakingWeights` multivariate distribution.

Remove calls to the assert_negative_support

In relation to the issue #5162 where the calls to the assert_negative_support function were removed. We should also remove the calls of this function inside the Multivariate module, the only class that uses this function is StickBreakingWeights.

pymc/pymc/distributions/multivariate.py

Lines 2286 to 2294 in f9e0dfd

	@classmethod
	def dist(cls, alpha, K, *args, **kwargs):
	alpha = at.as_tensor_variable(floatX(alpha))
	K = at.as_tensor_variable(intX(K))
	assert_negative_support(alpha, "alpha", "StickBreakingWeights")
	assert_negative_support(K, "K", "StickBreakingWeights")
	return super().dist([alpha, K], **kwargs)

Moreover, the function is being imported from the continuous.py:

pymc/pymc/distributions/multivariate.py

Lines 46 to 51 in f9e0dfd

	from pymc.distributions.continuous import (
	BoundedContinuous,
	ChiSquared,
	Normal,
	assert_negative_support,
	)

that will be deprecated in future versions of pyMC. Shouldn't we remove the calls and the import from this module?

Working on it!
