chore: drop `SEC_REGISTRY_IMAGE`
What does this MR do?
Drops hardcoded var in favor of project-level CI variable. This keeps the configuration centralized alongside username/password credentials for discoverability and allows us to copy-paste easily as we will be defining these using the new flattened structure as registry.gitlab.com/security-products/$CI_PROJECT_NAME
