feat: Enable cred setup for workflows created from templates (no-changelog) (#8240)

## Summary

Enable users to open credential setup for workflows that have been
created from templates if they skip it.

Next steps (will be their own PRs):
- Add telemetry events
- Add e2e test
- Hide the button when user sets up all the credentials
- Change the feature flag to a new one
