Description

• Renamed reuseable GHA that extracts/creates the Kubernetes namesapce from github Granch name. This forces the name to always only have SPSH-0000 and not SPSH-0000-2hfweojr. This change would affect 4 Namespace in the Devcluster and needs to get communicated.
• This changes enables us to decrease the complexity of the pipeline.
• This fixes the issue, that if i ran the Deployment to a Namespace manuelly, from a branch in this repo, that the ingress will be named after the branches ticket name of the branch of spsh-app-deploy, and does not take the ones i set via the GHA Inputs.
• This adds the feature, that the Databases on the Developer namespaces do not get deleted per default, but it has to get actively set.

Worked on DEV:
