Refer to SimpleGrantedAuthority instead of GrantedAuthorityImpl

GrantedAuthorityImpl has been replaced a couple of years ago with
SimpleGrantedAuthority and this commit fixes the documentation items
which weren’t updated to reflect this change.

Fixes gh-4163.

 An example of a "complex" `GrantedAuthority` would be an implementation that stores a list of operations and authority thresholds that apply to different customer account numbers. Representing this complex `GrantedAuthority` as a `String` would be quite difficult, and as a result the `getAuthority()` method should return `null`. This will indicate to any `AccessDecisionManager` that it will need to specifically support the `GrantedAuthority` implementation in order to understand its contents.
 
-Spring Security includes one concrete `GrantedAuthority` implementation, `GrantedAuthorityImpl`. This allows any user-specified `String` to be converted into a `GrantedAuthority`. All `AuthenticationProvider` s included with the security architecture use `GrantedAuthorityImpl` to populate the `Authentication` object.

 The first method returns the `Authentication` object that should replace the existing `Authentication` object for the duration of the method invocation. If the method returns `null`, it indicates no replacement should be made. The second method is used by the `AbstractSecurityInterceptor` as part of its startup validation of configuration attributes. The `supports(Class)` method is called by a security interceptor implementation to ensure the configured `RunAsManager` supports the type of secure object that the security interceptor will present.
 
-One concrete implementation of a `RunAsManager` is provided with Spring Security. The `RunAsManagerImpl` class returns a replacement `RunAsUserToken` if any `ConfigAttribute` starts with `RUN_AS_`. If any such `ConfigAttribute` is found, the replacement `RunAsUserToken` will contain the same principal, credentials and granted authorities as the original `Authentication` object, along with a new `GrantedAuthorityImpl` for each `RUN_AS_` `ConfigAttribute`. Each new `GrantedAuthorityImpl` will be prefixed with `ROLE_`, followed by the `RUN_AS` `ConfigAttribute`. For example, a `RUN_AS_SERVER` will result in the replacement `RunAsUserToken` containing a `ROLE_RUN_AS_SERVER` granted authority.

 The replacement `RunAsUserToken` is just like any other `Authentication` object. It needs to be authenticated by the `AuthenticationManager`, probably via delegation to a suitable `AuthenticationProvider`. The `RunAsImplAuthenticationProvider` performs such authentication. It simply accepts as valid any `RunAsUserToken` presented.
