Subject: [PATCH] test: migrate `stats/incr/nanme` to ULP-based assertions

Migrate the test cases for `stats/incr/nanme` from relative tolerance
assertions to ULP-based assertions using
`@stdlib/assert/is-almost-same-value`.

The ULP bounds were tightened to the minimum passing integer values: `0`
for the incremental accumulation test case and `3` for the test case
asserting the current accumulated value.
