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

Replaces the computed relative tolerance assertions in the fixture
loops with `isAlmostSameValue` ULP comparisons. The ULP bound was
tightened to the measured minimum of 1 ULP over the full Julia
fixture set.
