CI tests error with astropy 6.0

[olebole]

With Astropy 6.0, two CI tests produce an error:

______ ERROR collecting density_estimation/tests/test_bayesian_blocks.py _______

Full test log

Reason is that astropy.tests.helper.catch_warnings was deprecated in Astropy 5.1 and removed in Astropy 6.0:

• Removed deprecated deprecation, warning, and exception handling functionality provided by astropy.tests.helper. [#14670]

Hi,

Same issue after updating dependencies chain in Guix for astropy to 6.0.0.
