Request for GitLab CI Integration as an Alternative to GitHub Actions

[michsko544]

Hi Team,

I would like to propose adding GitLab CI as an alternative to GitHub Actions for our CI/CD pipeline. I attempted to configure GitLab CI on my own but encountered some difficulties running E2E tests. Having this integration available would be particularly useful.

Additionally, it would be great if the choice of CI/CD could be made available through the Medusa CLI.

Thanks
