🎨 formatting + linting in CI-CD

[jvdd]

This PR adds the following CI-CD checks:

• linting with ruff
• formatting with black (line-length = 88)
• sorting imports with isort

🤖 added a Makefile to, uhm, make it more convenient to call the lint & formatting commands

• Formatting the code: make lint
• Linting the code: make lint

Seems good!

Some questions:

• which commands should somebody use to run this locally?
• maybe add some information about this in the contirbuting.md

When I get these answers, I will continue my review.

[jvdd]

To run locally, just perform poetry install in the plotly_resampler cloned repo - this will install the dev dependencies from the poetry.lock file.

Once all (new) dev dependencies are installed, you can use the Makefile to

• format the code: make format
• lint the code: make lint
• and test the code (with coverage): make test

-> I updated the CONTRIBUTING.md with how you should run the formatting & linting (& testing) locally

Hope this answers your questions @jonasvdd

Does the CONTRIBUTING.md solve / answer your comments @jonasvdd ?
