Removing excluded users from ListUsers response

[willvedd]

Description

Removes excluded_users from the response of all SDKs as it was removed from OpenFGA with openfga/api#171.

This feature was originally a well-intentioned way to communicate any negations that may exist on public-typed wildcard (e.g. user:*) as a means of being abundantly clear about what a user:* result entails. However, as we discover more possible situations where excluded users could arise, we realize that we were making a premature decision about the API. We fully intend to re-add excluded_users at some point in the future but may or may not be a flattened list as previously implemented.

Please note:

• This is technically a breaking but is acceptable provided that the ListUsers API is still experimental
