Bug fix

Summary

On feature branches the variable $CONTINUE_BUILD isn't set. This is the reason why https://gitlab.gwdg.de/subugoe/emo/Qviewer/-/blob/develop/.ci-scripts/update-artifacts.sh#L15 never gets triggered on feature/bugfix branches.

In order to solve this, I added another condition that returns true if we are on a feature/bugfix branch.
