WIP: Testing some features of GitLab CI

Closed username-removed-25042 requested to merge pserwylo/fdroid-website:test-branch into master

This is a throw-away MR used to test the Environments feature and see if it would be useful for the fdroid-website project. The goal is to have the GitLab UI show a URL where you can view the live hosted version of the website for each specific branch.
