Modernise and fix most notebooks

[gijzelaerr]

This PR:

• Went through the notebooks and made compatible with the latest libraries listed in requirements.txt
• There is a bug in librosa 0.10 which breaks the .showwave() function when used with matplotlib >3.8, so I fixed the version to matplotlib<3.8
• I added a helper Makefile to quickly setup and open a juputer lab locally with the listed versions installed. Just run make, to start a notebook server. Should work on OSX and Linux, if python3 and make are installed.
• I've cleared all cells and reran the notebook before committing.
• Adds a nbmake github action to test the notebooks

Some notebooks have broken upstream dependencies or are example material, not sure what to do there:

FAILED adtlib.ipynb:: - ModuleNotFoundError: No module named 'ADTLib'
FAILED evaluation_beat.ipynb:: -     https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
FAILED evaluation_chord.ipynb:: - TypeError: evaluate() missing 4 required positional arguments: 'ref_intervals', 'ref_labels', 'est_intervals', and 'est_labels'
FAILED exercise_genre_recognition.ipynb:: - NameError: name 'mfcc_busta' is not defined

Thank you! this is awesome. I will review soon.

Hello @gijzelaerr, I've been going through the PR, and in general everything looks very good. Something that is unclear is whether you meant to include all the docker files. We currently do not support docker, so if that is a feature that you want to add, I recommend creating a different PR so that we can discuss. The notebook updates will be welcome otherwise.

I'm a little late to the party, but I noticed you all aren't using a notebook review tool and wanted to invite you to review this pull request with GitNotebooks: https://gitnotebooks.com/iranroman/musicinformationretrieval.com/pull/61

It lets you do things like comment on rendered markdown and code cells, so might be an easy win for your PR reviews.
