Description:
Currently, Bitbucket Pipelines supports advanced triggers for tag creation (as documented here: https://support.atlassian.com/bitbucket-cloud/docs/pipeline-start-conditions/#Trigger-type]). However, there is no support for triggering pipelines on tag deletion events.

Feature Request:
Please add support for advanced pipeline triggers that can respond to tag deletion events. This would enable teams to automate workflows such as cleanup tasks, notifications, or other actions when a tag is deleted from the repository.

Current Limitation:
Only tag creation can be used as a trigger condition; tag deletion is not currently supported.

Benefit:
This feature would provide parity with other Git event triggers and enhance automation capabilities for Bitbucket users.
