This worked, as we can see from the last commit b1fa81c which was done automatically by https://github.com/grafana/mimir/actions/runs/13659224117.

I will now delete the line making the CI run even though I was not renovabot and ask for reviews.

don't we need to add some token to the update_pr step at the bottom too?

Good question but we don't as we only need the token when pulling content from what I've tested.
