feat: make jupyter a dev dependency

[deepeshaburse]

Description

This PR helps to make jupyter a dev depenency. To do this:

1. jupyter has been removed from requirements.txt.
2. 'jupyter' has been shifted to "dev" from "install_requires" in setup.py.

Fixes #2457

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist:

• No style issues: $ pre-commit run (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: $ python run-tests.py --all
• The documentation builds: $ python run-tests.py --doctest

You can run unit and doctests together at once, using $ python run-tests.py --quick.

Further checks:

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works

@deepeshaburse you will have to debug and fix the failing tests in order for us to review this PR. You can click on the details button of any of the tests and it will redirect you to the logs. The tests are failing with the error -

Traceback (most recent call last):

ModuleNotFoundError: No module named 'importlib_metadata'
ERROR: InvocationError for command /Users/runner/work/PyBaMM/PyBaMM/.tox/mac-windows-unit/bin/python run-tests.py --unit (exited with code 1)

I am guessing that jupyter was installing importlib_metadata for us, but we now might have to explicitly list it as one of our dependencies.
