Updated ndarray_adapters_test to be compatible with newer treescope release

[kochkov92]

Previously np_adapter.get_array_summary would return str repre, but with recent treescope updates it returns Siblings object. This PR simply extracts text entries from Siblings to mimic the old test.

@danieldjohnson - do you think this would work?
I'd love to be able to run latests versions of treescope & penzai together (without disabling some tests).

Thanks for catching this, and sorry for the late response!

Would you mind changing it to instead use treescope.lowering.render_to_text_as_root to convert it to string instead of parsing the Siblings object manually? This should be more robust to future changes.

Also, FYI, there is an issue with the Penzai and Treescope PyPI packages that is preventing me from making new releases at the moment, so it might take some time before I am able to get this change into a release.

Nice - I was searching for this functionality within treescope but failed to quickly find it last time. Thanks for pointing it out!
