Sync integration to GitLab CI variables

Hi there,

We are thoroughly enjoying using Dopper, so thank you!

The docs already cover using the Doppler CLI in CI jobs, but sometimes this is not possible. It would be perfect if Doppler could sync with GitLab’s built-in CI/CD variable section. (GitLab CI/CD variables | GitLab).
They have an API for this; Project-level CI/CD variables API | GitLab
Less important, but there are also group level variables that would be handy to sync.

I envisage this working exactly like the GitHub Actions sync, but for gitlab dot com and self-hosted instances.

Thank you in advance.
