[FEAT] Beta paginated_api_keys function

[nwithan8]

Description

• Adds new function paginated_api_keys to User to return a paginated list of API keys, rather than unpaginated from api_keys

NOTE: This beta function exists in the GA User class rather than in a separate Beta\User class because this method is an instance method. It would only be accessible on Beta\User objects, which wouldn't have any other of the existing functions that exist on the User object. They would either have to be entirely re-implemented or a converter between User and Beta\User would have to be introduced; both strategies would add extra overhead and require changes to the end-user's workflow.

More recent major versions of our library have effectively removed this issue by our re-architecture into services that make it easier to separate beta functions from GA functions. For now, a docstring has been added warning users that this new function is in beta.

Testing

• Add unit test to confirm/validate data coming back from new function/endpoint, test pagination capabilities
• Add cassette

CI is failing because security scan is failing because it's trying to install the latest version of roave/security-advisories which conflicts with sub-dependency requirements, likely due to EOL PHP version support.

roave/security-advisories does not offer any tagged version of its library other than dev-latest, so we can't "pin an older version" to overcome this issue.
