[Epic:`.NET`] Migrate old NestJS dsg to new convention (changing project name, docker image name, ECR repository) `generator-nodejs-nest`. DSG catalog needs to handle the generator renaming based on version. i.e. for NodeJs generator, if version is before 4.0.2, the fullname would be hardcoded to `data-service-generator`

• build-manger: make sure there is no hard-coded "data-service-generator"
• local DSG controller: make sure there is no hard-coded "data-service-generator"
• rename the helm chart into generator-controller
