build: remove 'ipykernel' dependency

[marcofavoritobi]

Proposed changes

The dependency ipykernel is not used directly from any module in black-it, hence it should not be declared as main dependency of the package. This PR removes it from the section tool.poetry.dependencies in pyproject.toml, and recomputes poetry.lock by using poetry lock --no-update.

Potentially breaking change if packages dependent of black-it use ipykernel directly (unlikely).

We should see if there are any examples/documentation that need to be updated

I don't think so, for the following reasons:

• ipykernel is never used directly, neither in docs nor in examples.
• documentation code and examples code rely on development dependencies, and ipykernel is included in them, due to e.g. nbmake, jupyter etc.
• ipykernel is needed by ipywidgets, which atm is a main dependency; therefore, ipykernel is always installed, hence nothing changed from the library perspective.

Closing in favor of #78, which includes this one.
