fix(core): ensure default path is set for control flow migration 
When running the control flow migration via `ng update`, the path parameter could be undefined. This change ensures a default value of './' is used when no path is explicitly provided, making the migration work consistently between `ng update` and `ng generate` commands.

Fixes #63294
