New issue 912: Registration - 3.3.  Client Registration Error Response example is missing schema
https://bitbucket.org/openid/connect/issue/912/registration-33-client-registration-error

Nat Sakimura:

the example code seems to be wrong. 

It states: 


```
#!http

  HTTP/1.1 400 Bad Request
  WWW-Authenticate: error="invalid_redirect_uri",
    error_description="One or more redirect_uri values are invalid"
  Cache-Control: no-store
  Pragma: no-cache
```

As you can see, this is missing the required authorization schema, which in our case is "Bearer". 

It should be: 


```
#!http

  HTTP/1.1 400 Bad Request
  WWW-Authenticate: Bearer error="invalid_redirect_uri",
    error_description="One or more redirect_uri values are invalid"
  Cache-Control: no-store
  Pragma: no-cache
```
The same is true for the ReadError.
