[SIGMON-201] test notebooks reports

Context

• task: https://its.cern.ch/jira/browse/SIGMON-201
• lhc-sm-notebook MR: lhc-sm-notebook!13 (merged)

What was done

• Notebooks' last cell refactored: path_to_notebook, report_destination_path_template and report_filename_template variables extracted and moved to the top (just below the imports) so they could be overwritten by the injected parameters:

• The content of the HTML report and the CSV files produced by the notebook is asserted in the tests. CSVs are compared with the reference files as they are (==); HTMLs are preprocessed similarly to the resulting notebooks.

• magic functions in nQPS_Viewer.ipynb fixed

TODO

• documentation https://its.cern.ch/jira/browse/SIGMON-199

QA

• code was not unit tested, because it's lhc-sm-hwc
• notebooks passed: https://gitlab.cern.ch/LHCData/lhc-sm-hwc/-/jobs/17660303

Review objectives

• assessment of code functionality
• assessment of code quality
• identifying potential refactorings / logic common to other projects
• knowledge sharing
