Merge branch 'main' into v2

* main:
  feat(stdiscosrv): configurable desired not-found rate
  chore(blobs): generalised blob storage
  chore(stdiscosrv): path style s3
  feat(ursv): add os/arch/distribution metric
  chore(strelaypoolsrv): limit number of returned relays
  build(infra): run in Docker environment for pushes
  chore(stupgrades): expose latest release as a metric
  feat(api, gui): allow authentication bypass for metrics (#10045)
