feat: remove gitlab CI and create github CI

Still to be done: the previous .env file, which was treated as a environment file (and not variables) by GitLab CI, must be managed by GitHub secrets.

Could be useful: https://github.com/marketplace/actions/create-env-file

@leoguillaume If you know GitHub Actions and secrets, let me know what you think, especially regarding the use of env files in GitHub (not sure on how we should achieve/convert that). Available to talk quickly about it after you have a quick look

@bolinocroustibat Can we set up the bot to always respond with the "maintenance message" in this PR, so we can prioritize merging it and validating the deployment pipeline (including any tests) before the other PRs are ready to be merged and tested?

Sure, but this is a draft PR and not ready to be merged, as I'm not sure on how to manage the env file in the CI/CD workflow file. I would need some help first on that. If you can help this week you can commit on that one, otherwise I would advise to merge the other PRs and continue on GitLab in the meantime.

I am wondering, in fact the two pipelines are exactly the same except the env name.
Maybe this CI can be simplified by having just one single file if there is a way to select the environement as the name of the branch. It should be easy. What do you think about it ? @bolinocroustibat

Yes it should be doable indeed, choosing the environment depending on the branch. I'll have a look at that tomorrow

@dtrckd It's done on the same PR. I realized there were a few other stuff not working. Have a look when you have the time.

The build_and_deploy job, in a single file, looks really cleaner and simpler now, good job!
