Hello APISIX Team.

Currently I Have enabled the API Key based authentication using keyAuth in apisix for my apisixroute. In this

    authentication:
        enable: true
        type: keyAuth        
        keyAuth:
          header: "Authorization"      

curl  -H "Authorization: <api-key>" http://0.0.0.0/api

      In the above the authentication  happens from "Authorization" header with APIKEY as value. But I wanted add "Bearer "
      
      
      Could you please help how to add it so that my authentication will look like as below

curl  -H "Authorization: Bearer <api-key>" http://0.0.0.0/api
