Middleware

I think file configs are cleaner than having a billion labels. This is not required, but it’s nice to have.

# middleware.yaml
http:
  middlewares:
    BlueskyHeaders:
      headers:
        accessControlAllowMethods:
          - GET
          - OPTIONS
          - PUT
          - POST
          - DELETE
        accessControlAllowHeaders: "*"
        accessControlAllowOriginList: "*"
        addVaryHeader: true
