fix: fixed problem where chart couldnt be deployed

problem was occuring because of the value 'username' in postgresql.auth.username in values.yaml. When setting this value postgresql automatically also sets a password for the root user which couldnt be found in our backend-secrets-postgres.yaml file because we only set a datasource password an no root password.
