ci: Use pixi for book build (#85)

* Update GitHub Actions.
   - actions/checkout@v3 -> actions/checkout@v4
   - actions/setup-python@v4 -> actions/setup-python@v5
* Use prefix-dev/setup-pixi to setup pixi and load environment.
   - Remove use of ROOT Docker image.
* Use pixi commands to build Jupyter book
   - This significantly speeds up the build in CI by multiple minutes.
* Use uvx for lint workflow.
* Use root_base in Binder postBuild.
* Update Binder Python to 3.12.
