test: migrate constants/float32/ln-ten to ULP-based assertions

[Planeshifter]

Resolves a part of #11352.

Description

What is the purpose of this pull request?

This pull request:

• migrates the tests of constants/float32/ln-ten from an EPS-based tolerance to ULP-based assertions using @stdlib/number/float32/base/assert/is-almost-same-value.
• uses a single named constant ULP = 0. This is the measured minimum: the constant equals lnf(10) exactly (tests pass for N = 64, 4, 2, 1, and 0, and were run twice at the final value).

Questions
