Issue/Feature description

As reported by https://github.com/cgibbs35 in chainguard-dev/edu#1605

Describe the bug
when deploying thanos as a sidecar with the sidecar configuration, the reloader was never triggering resulting in a prometheus crashback loop.

To Reproduce
deploy prometheus community helm chart using chainguard latest images. following these directions. here

using both chainguard latest for prometheus and thanos results in failure, however switching the thanos image back to the standard quay image the reloader config works and prometheus starts up.

Expected behavior
both pods should start up and thanos sidecar should be deploying its reloader configs to rebuild the prometheus.yml for prometheus to startup
