enhancement: allow AWS Federated users to be granted permissions

[frco9]

Description

In this issue @colonmelvin raise the fact that lake formation permissions did not allowed to use Federated Users ARN.
It seems, @chrisbulgaria forgot to adapt his PR before it got merged to support this.

Thus this small fix will allow to create LF permissions for federated users that logged in using GetFederationToken
