Bump Jupyter-Notebook and dependencies to fix build error

[tompollard]

As discussed in #89, the website build is currently failing with a "Sphinx version error":

Sphinx version error:
The sphinxcontrib.applehelp extension used by this project needs at least Sphinx v5.0; it therefore cannot be built with this version.
Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.9.19/x64/lib/python3.9/site-packages/sphinx/registry.py", line 430, in load_extension
    metadata = setup(app)
  File "/opt/hostedtoolcache/Python/3.9.19/x64/lib/python3.9/site-packages/sphinxcontrib/applehelp/__init__.py", line 230, in setup
    app.require_sphinx('5.0')
  File "/opt/hostedtoolcache/Python/3.9.19/x64/lib/python3.9/site-packages/sphinx/application.py", line 415, in require_sphinx
    raise VersionRequirementError(version)
sphinx.errors.VersionRequirementError: 5.0
