Enhance script for feature branches

The workflow just is for the develop branch.

We also need it for feature branches, because we want to create a package from that feature branch. Otherwise, we cannot test and cannot add it in one of our projects composer.json for testing. E.g. the pipeline of the mobimo component project does not run anymore.

I will add $CI_COMMIT_BRANCH == "develop" $CI_COMMIT_BRANCH == "/^feature/.*" for the rules.

@jurgenhaas Can you confirm? Then I will do the job.
