CLN: remove Hypothesis warning during test

```plain
hypothesis\_settings.py:193: HypothesisDeprecationWarning: The timeout setting can 
safely be removed with no effect.
```

Starting with 4.0.0 released in Jan, the timeout setting does [nothing](https://github.com/HypothesisWorks/hypothesis/commit/2b9506b7120c2f0593539c1e5d9b526d7ec1377f).

```plain
    The timeout setting has been deprecated and no longer does anything.

    default value: not_set

    The timeout setting can safely be removed with no effect.
```

Bump dependency from `>=3.8.2` and remove setting.
