feat: Add addAdventure function to adventureService

The code changes include adding a new function called addAdventure to the adventureService module. This function is responsible for sending a POST request to the corresponding API endpoint to add a new adventure. If the request is successful, the adventure is added to the local plans array and a success toast is displayed. If the request fails, an error toast is displayed. This functionality allows users to add adventures to the planner page.
