How to report HttpErrors.Forbidden from authenticate action

Suggestion
I have implement JWTStrategy
every thing working fine. now I am trying to further authenticate according to user roles
e.g if logged in user is not `ADMIN` raised `HttpErrors.Forbidden` error

current strategy-adapter.js code only raise InternalServerError if I pass error in cb() of JWTStrategy

I have changed strategy-adapter.js
`reject(new rest_1.HttpErrors.InternalServerError(error));` to
`reject(error);` and pass
`cb(new HttpErrors.Forbidden(), false);` in `auth-strategy.provides.ts`
which working according to my requirement
my question is there best way to implement changes in my code instead of changing in @loopback/authentication module directly

Existing CODE
`@loopback/authentication/strategy-adapter.js `

```js
strategy.error = function (error) {
reject(new rest_1.HttpErrors.InternalServerError(error));
};
```

Start by reading @loopback/authentication/strategy-adapter.js and the auth-strategy.provides.ts callback usage shown in the issue. Trace how strategy errors become HTTP errors and determine what supported extension point would preserve HttpErrors.Forbidden without editing the module directly; done means the role-authentication error is propagated through the documented application code path.
