## [Dashboard] Fix: Temporarily remove Webhooks from sidebar

## Notes for the reviewer

Commented out the Webhooks section in the project sidebar until we resolve a scrolling issue. Also removed the unused BellIcon import.

Verify that the Webhooks option no longer appears in the project sidebar navigation.
