Feature/environments
Summary
Changes coming in with this MR:
- only the main branch is deployed to https://subugoe.pages.gwdg.de/ahiqar/website/
- other branches are deployed to their respective environments (cf. https://gitlab.gwdg.de/subugoe/ahiqar/website/-/environments)
- after a merge to main, all existing environments are checked. If they belong to a branch that no longer exists, they are deleted.
How to test
- check out this branch, add some changes and push it. Your changes should appear in the environment, but not on the main page.
- the deletion of the environment cannot be tested since it takes effect only after the merge.
Closes #15 (closed), #18 (closed).
