docs: clarify delete_subscription should return success if subscription not found

[Mairuis]

Summary

• Add documentation note to delete_subscription method clarifying that it should return success=True when the subscription no longer exists on the external service
• This ensures idempotent behavior - if the goal is to remove the subscription and it's already gone, that's a success

Test plan

• Documentation change only, no code changes

Summary of Changes

Hello @Mairuis, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the documentation for the delete_subscription method, specifically addressing its behavior when a subscription is not found on an external service. The update ensures that the method's expected outcome aligns with idempotent principles, treating the successful removal of an already non-existent subscription as a success rather than an error. This change improves clarity for developers and promotes more robust integration with external services.

Highlights

• Documentation Update: Added a new documentation note to the delete_subscription method in python/dify_plugin/interfaces/trigger/__init__.py.
• Idempotency Clarification: The note clarifies that delete_subscription should return success=True if the subscription is already absent from the external service, ensuring idempotent behavior.

Code Review

This pull request adds a helpful clarification to the delete_subscription method's docstring, specifying that it should return a success status if the subscription is already deleted. This promotes idempotent design. My review includes a small suggestion to refine the wording for better clarity and conciseness.
