Fix a regression in webhook-based autoscaler (#1596)

The regression resulted in the webhook-based autoscaler be unable to find visible runner groups and therefore unable to scale up and down the target RunnerDeployment/RunnerSet at all when the webhook-based autoscaler was provided GitHub API credentials to enable the runner groups support. This fixes that.

The regression was introduced via #1578 which is not released yet. Users of existing ARC releases are therefore not affected.
