Adding an editable "access denied" page

[aybarsyildiz]

Description

It would be a good idea to add a callback for the error page on the Keycloak middleware.

For example, the middleware setup could look like this and it will be possible to create your own 401 Unauthorized pages.

app.use(keycloak.middleware({
  logout: '/logout',
  admin: '/',
  error: '/error'
}));

Motivation

On our project with my team, we are using node.js and Keycloak.
For the unauthorized page, we had some issues editing it.
