Run pipeline after each push?

I had an issue with !47 (merged) where the pipeline failed and thereby showed me an error that I had made. But this only happened after merging! I then fixed it with the new MR !58 (merged). We could configure the pipeline to run every time commits are pushed to GitLab (https://codebase.helmholtz.cloud/help/ci/pipelines/merge_request_pipelines.md#prerequisites) and not just after merging an MR.

Pro: Errors are found earlier

Con: The type of error caught like that is not likely to occur often.
