Describe the bug
When loading blueprints from an OCI registry I always get the error Blueprint file does not exist

To Reproduce
Steps to reproduce the behavior:

1. Create a Blueprint
2. Upload the Blueprint with oras
   ./oras push larsl.dev:5050/larsl-net/authentik-config/blueprints/larsl-stages-base:latest larsl-stages-base.yaml:application/vnd.goauthentik.blueprint.v1+yaml
3. Try loading the Blueprint with authentik
   oci://larsl.dev:5050/larsl-net/authentik-config/blueprints/larsl-stages-base:latest
oci://ghcr.io/larsl-net/blueprint/larsl-stages-base:latest

Expected behavior
The Blueprint loading over OCI works.
