Jupyter Book v2 migration issues

[matthewfeickert]

In PR #107 we migrated to Jupyter Book v2, which had some associated issues.

• Binder configuration no longer seems to work as expected.
  • c.f. https://github.com/orgs/jupyter-book/discussions/2496
• Launch buttons for Google Colab are disabled.
  • c.f. https://github.com/orgs/jupyter-book/discussions/2511#discussioncomment-15095723

Things that existed in Jupyter Book v0

pyhf-tutorial/pixi.toml

Line 39 in 6b4c464

jupyter-book = "0.15.1.*"

that I'm not sure how to do now:

• Set execution timeouts

pyhf-tutorial/book/_config.yml

Lines 7 to 8 in 6b4c464

	execute:
	timeout: 210 # seconds

• Set launch buttons for Binder and other tools

pyhf-tutorial/book/_config.yml

Lines 23 to 27 in 6b4c464

	# Launch button settings
	launch_buttons:
	notebook_interface: jupyterlab
	binderhub_url: https://mybinder.org
	colab_url: https://colab.research.google.com

PRs #112 and #113 were also things that needed to be fixed.
