-# The section is needed to drop write-all permissions that are granted on
-# `schedule` event. By specifying any permission explicitly all others are set
-# to none. By using the principle of least privilege the damage a compromised
-# workflow can do (because of an injection or compromised third party tool or
-# action) is restricted. Currently the worklow doesn't need any additional
-# permission except for pulling the code. Adding labels to issues, commenting
-# on pull-requests, etc. may need additional permissions:
