chore: integ tests don't work on fork (#780)

* chore: integ tests don't work on fork

Because of the `pull_request_target` event we are trying to checkout the
source from the base repo instead of the fork.

Pass the correct repository name as an argument.

* Also update expression that requires human appproval on integ tests

* chore: self mutation
