Task Description (Required)

When the common logic in the CLI repo was moved to he bridge repo, the unit tests at https://github.com/redhat-ai-dev/rhdh-ai-catalog-cli/blob/main/pkg/cmd/cli/kserve/kserve_test.go and https://github.com/redhat-ai-dev/rhdh-ai-catalog-cli/blob/main/pkg/cmd/cli/kubeflowmodelregistry/kfmr_test.go were not ported to https://github.com/redhat-ai-dev/model-catalog-bridge/tree/main/pkg/cmd/cli/kserve and https://github.com/redhat-ai-dev/model-catalog-bridge/tree/main/pkg/cmd/cli/kubeflowmodelregistry because they were cobra command / CLI based

Reintroduce those unit tests in the bridge repo in a non cobra command fashion.
