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

Replace relative tolerance assertions with ULP difference assertions
using `@stdlib/assert/is-almost-same-value`. The quantile function
returns non-negative integers, and both the JavaScript and C
implementations reproduce the Julia fixture values exactly, so the
minimum required ULP value is `0`.
