Add Gitpod for Easy Contributions

[ThomasSanson]

Is your feature request related to a problem? Please describe.
Contributing to a new project often involves setting up a local development environment, which can be time-consuming and may deter potential contributors. This process can be particularly frustrating when the contributor simply wants to make a quick fix or add a small feature.

Describe the solution you'd like
I propose the addition of Gitpod to this project. Gitpod is a dev environment that spins up in seconds directly in your browser, allowing contributors to start coding immediately without the need to set up a local development environment. This would involve adding a .gitpod.yml file to configure the Gitpod workspace.

In addition, the contribution documentation located at this link would need to be updated to include instructions on how to use Gitpod for contributions.

Describe alternatives you've considered
An alternative could be to provide a detailed guide on setting up a local development environment for this project. However, this would still require time and effort on the part of the contributor, and would not provide the instant access that Gitpod offers.

Additional context
By lowering the barrier to entry for new contributors, we can encourage more participation in the project and potentially increase the speed and diversity of improvements and new features. I am happy to work on this if you agree.

I totally approve, that's what I use normally. I love the fact that by default, the environments are more performant than GitHub codespaces. I just don't configure it, and redo some steps to set the Python env and version, and install requirements.

Last time I tried the GitHub Codespaces with the devcontainers contributed by a user didn't work, and couldn't load.
