Deprecated argument names in hdbscan_.py

[joaquindas]

Sklearn deprecated force_all_finite param for check_array(). Docs here. There is a deprecation warning when fitting the model. check_array function is used twice in hdbscan_.py. Changed both to new param naming ensure_all_finite, functionality is identical.

This change also increases the minimum required scikit-learn version from 0.2 to 1.6. Maybe it is worth testing which version is available at run-time to keep support for older scikit-learn versions?

If dependencies were declared in pyproject.toml, it would be straightforward to specify scikit-learn version for given python versions. Is there interest in setting that up instead of requirements.txt?
