Incorrect labeled event fired when label is Deleted from PR

[Sumit189]

Description

When a label is removed from a Pull Request (PR) in Gitea, the system triggers the labeled event, which is incorrect. The expected behavior is that the unlabeled event should be fired when a label is removed from a PR.

Steps to Reproduce:

1. Open a PR in Gitea and add a label to it.
2. Remove a label from the PR.
3. Observe that the labeled event is triggered instead of the expected unlabeled event.

Expected Behavior:
The system should fire the unlabeled event when a label is removed from a PR.

Actual Behavior:
The system fires the labeled event when a label is removed from a PR.

Proposed Fix:
Ensure the correct unlabeled event is triggered when a label is removed from a PR.
