fix: ignore dependent branches on snapshot destroy (#599)

Description

Ignore dependent branches on snapshot destroy

⚠️ The existence of dependent branches means that other snapshots from other branches are built on this snapshot. This is a dangerous change, when using the force option it will remove all dependencies of the snapshot.

When approving, make sure that this is really what we want!
