Weichen Xu 11fac232c8 [MINOR] Improve flaky NaiveBayes test
### What changes were proposed in this pull request?
Improve flaky NaiveBayes test

Current test may sometimes fail under different BLAS library. Due to some absTol check. Error like
```
Expected 0.7 and 0.6485507246376814 to be within 0.05 using absolute tolerance...

```

* Change absTol to relTol: The `absTol 0.05` in some cases (such as compare 0.1 and 0.05) is a big difference
* Remove the `exp` when comparing params. The `exp` will amplify the relative error.

### Why are the changes needed?
Flaky test

### Does this PR introduce _any_ user-facing change?
no

### How was this patch tested?
N/A

Closes #31004 from WeichenXu123/improve_bayes_tests.
