Fix typo in parameter name: mode_owner_cap to model_owner_cap

[cudiHAHA]

Description of Changes:
In three files (cli_cluster.py, ig_post_planner.py, trip_planner.py), a typo was found in the parameter name: mode_owner_cap instead of model_owner_cap. This fix resolves the error and ensures consistent parameter naming across all examples.

Changes:

1. In cli_cluster.py:

   • Changed parameter mode_owner_cap to model_owner_cap in the run_cli_cluster_example function.

2. In ig_post_planner.py:

   • Changed parameter mode_owner_cap to model_owner_cap in the run_ig_post_planner_example function.
   • Updated the InstagramPostPlanner constructor call to use model_owner_cap.

3. In trip_planner.py:

   • Changed parameter mode_owner_cap to model_owner_cap in the run_trip_planner_example function.
   • Updated the TripPlanner constructor call to use model_owner_cap.
