[JobRunnerGroup] Command output after creating JRG is not formatted well

[foxish]

signadot jrg apply -f ./job-runner-group.yaml
Applied runner "xyz-test-jobs" ("https://app.signadot.com/testing/runner-groups/xyz-test-jobs")

We should make this more consistent with how the output looks in the case of sandbox apply.

$ signadot sb apply -f ./frontend.yaml
Created sandbox "frontend-fork" (routing key: 0b3qcydg4h9f2) in cluster "signadot-staging".
