The CatalogSource''s pod is either injected with the right pod.spec.securityContext and pod.spec.container[*].securityContext values to allow the pod to run in Pod Security Admission(PSA) controller''s `restricted` mode, or doesn''t set these values at all, in which case the pod can only be run in PSA `baseline` or `privileged` namespaces. By default, SecurityContextConfig is set to `restricted`. If the value is unspecified, the default value of `restricted` is used.  Specifying any other value will result in a validation error. When using older catalog images, which could not be run in `restricted` mode, the SecurityContextConfig should be set to `legacy`.
