Update tutorials and improve tutorial testing framework

[jngrad]

Description of changes:

• tutorial 05 raspberry electrophoresis (fixes Improve tutorial tests #3058)
  • plot the final trajectory in a matplotlib 3D plot
  • add test to check the raspberry traveled a longer distance over the axis of the E-field
  • test the sample .dat file as well
• tutorial 01 Lennard-Jones (fixes Use published result to check LJ rdf in tutorials test #3185)
  • plot and test the experimental RDF against the theoretical RDF
• tutorial 04 LB Part 4 solution script
  • added the solution script in the HTML output and fixed its test
• use AST to process Jupyter notebooks containing matplotlib code (fixes Use AST parser in the tutorial test logic #3215)
• fix CMake dependency resolution for tutorials

Further considerations:

• the theoretical RDF discussion in tutorial 01 may break the flow of the lecture and could be moved to the bottom of the notebook if necessary
• the new html_runner test fixture takes 7 seconds to run, which is noticeable when running a specific tutorial test with make -j$(nproc) check_tutorials ARGS='-R tutorial_01' for troubleshooting purposes
• new AST processing logic
  • enables a much more reliable handling of IPython magic commands that prevent the matplotlib command plt.show() from generating a picture in some tutorials (e.g. 04 Part 2)
  • requires a lot of calls to hasattr (e.g. importlib_wrapper.py#L388-L395), which could make importlib_wrapper.py fragile; please let me know if you're aware of a better strategy
  • doesn't use ast.NodeTransformer as we need to write the transformed code to disk to get clean tracebacks and create intermediate files for CMake dependency resolution
