Add CI checks for input arguments, spelling, more?

[Diewertje11]

Look up what kind of checks we can add to assure code quality:

• [x] Check for correct amount of arguments in functions
• [x] Check for if functions exist if they are called
• [ ] Spelling checks

Pylint is added to kso_utils in MR 166 in kso_utils.

However, note: Pylint is not picking up all errors. In project.py we are calling for tutorial_utils.get_annotator() and this one does not exist in tutorial_utils. However, we do not get an error for this, while we should. This might be a bug in Pylint and needs further investigation.

Also note, currently we install pytest and pylint separately when we do the tests, we might want them to just be included in the container. If so, we need to change this.

Still need to do:

• [x] Add pylint to kso, so that it can also run on the NB (maybe use nbqa to do this)
• [x] Decide where to have pylint and pytest installed
• [x] Currently the pylint test runs in the dev container, which will give a problem when we add new packages to the requirements, since this will not result in an update in the container. We need to discuss how we can fix this.

MR 181 in kso_utils fixes the problem of not recognising the get_annotator as error. The other to-do's are not done yet.

The spelling check we have included in another issue.

All other points are resolved in the commits where we removed the submodule of kso_utils and converted it into a folder. (commit e755c7c)

It was decided that pylint and pytest were only installed for testing and not in the requirements, since we do not need it anywhere else, so we do not want to make the container include even more packages.
