fix(dependabot-automerge): calling gh label without repository

Workflows fail with
failed to run git: fatal: not a git repository
  (or any of the parent directories): .git

The problem is that there is no checkout sometimes when this action is
called, thus no git directory.
See https://github.com/grafana/otlp-gateway/actions/runs/16214262982/job/45780063018

Easy fix is to just provide the repo name.
