Why: pushing in-house images to the internal-CA artifactapi registry fails `x509: certificate signed by unknown authority` with the upstream buildx plugin (and `:latest-insecure` does not fix it — buildkit still verifies the registry cert). The fix is the CA-baked plugin image now published at `artifactapi.k8s.syd1.au.unkin.net/docker-internal/plugin-docker-buildx` (unkin/plugin-docker-buildx v0.1.0). How: add that image (bare + `:latest`) to `WOODPECKER_PLUGINS_PRIVILEGED` in the au-syd1 overlay so it may run privileged. Existing upstream entries kept so current repos are unaffected until they switch over. Next: ghp `.woodpecker` switches its buildx step to this image, then ghp re-tags and its push succeeds.
