Support of ipywidgets 8.x

[dou-du]

Currently, the widget is only supporting ipywidgets < 8.x. We need to update the widgets once the "widget-cookiecutter" is updated for ipywigdets 8.x.

Hi @dou-du, I remember that you close the issue you report in widget-cookiecutter, something about the update ipywidget is not working? I can not find it anymore. Is that related and how you fix that?

The error is not from the cookiecutter template. I upgrade the periodic table, which is working fine. However, it is still a myth to make the brillouin zone widget working. I am going to try to upgrade bandsplot soon.

Okay, thanks! Please try to document a bit of what you did to make it work, to avoid future maintenance of other packages like this one.
