Auto-create docker-registry secret fails if namespace does not exists

Describe the bug

Auto-create docker-registry secret fails if namespace does not exists. Everytime a new review environment is created, the first run fails, because it could not create the secret.

[INFO] --- Create registry pull secret: gitlab-registry
Error from server (NotFound): error when creating "STDIN": namespaces "foo" not found

Expected behavior

Secret is created, job doesn't fail.

Actual behavior

Job fails. Nothing is deployed.

The issue was reproduced using:

• Version of the template: 4.0.1 legacy template
• GitLab server(s): Self-hosted

Configured GitLab CI project or group variables:

• CI_DEPLOY_USER is set
• CI_DEPLOY_PASSWORD is set
