Subject: [PATCH] test: migrate `stats/base/dists/hypergeometric/skewness` to
 ULP-based assertions

Replaces relative tolerance assertions with ULP difference assertions
using `@stdlib/assert/is-almost-same-value`. The maximum observed ULP
difference over the fixture set is 1 for both the JavaScript and native
implementations, so 1 is the minimum bound which passes.
