Replaced scipy array by numpy array in dendrogram

[HugoDelatte]

With new version of scipy 1.12, scipy.array fail with AttributeError: Module 'scipy' has no attribute 'array'.
I've simply replaced scipy.array by numpy.array.

Code PR

• I have read through the contributing notes and understand the structure of the package. In particular, if my PR modifies code of plotly.graph_objects, my modifications concern the codegen files and not generated files.
• I have added tests (if submitting a new feature or correcting a bug) or
  modified existing tests.
• For a new feature, I have added documentation examples in an existing or
  new tutorial notebook (please see the doc checklist as well).
• I have added a CHANGELOG entry if fixing/changing/adding anything substantial.
• For a new feature or a change in behaviour, I have updated the relevant docstrings in the code to describe the feature or behaviour (please see the doc checklist as well).

💃 Thanks! A little frustrating that this was removed in a minor release with no changelog note but this certainly looks like the correct solution.

Thank you for the PR, @HugoDelatte . The community's contributions to our open source libraries are a big reason Plotly and Dash are so popular.

If you have the time to tackle other issues, we would be thrilled 🤗

Thank you for this. I noticed that this fix is not available with the latest release on pypi (also listed as version 5.18.0 from last October), which came up when troubleshooting with a colleague using the latest scipy.

hi @asoltis
Can you please share your code that throws an error?

I just the code from issue number 4495, and it seemed to work for me.

Adam,

I was just saying I noticed that the fix referenced in this thread is not available in the plotly release currently available through pypi, thus upgrading plotly through pip did not fix the issue (we downgraded scipy to get it to work, as referenced in your linked thread). I imagine this will be included with a new plotly release, but I was commenting that it is not currently part of the available pypi package.

hi @asoltis
This should now be available in the new Plotly v5.19.0. Try it out and let us know if it doesn't work.

I just gave the new v5.19.0 a try and can confirm that the dendrogram function ran successfully with scipy 1.12.0 installed. Thanks!
