docs: Allowed Query Params for Authentication

Fix documentation for "Allowed Query Params for Authentication"

Summary

The documentation for allowed query parameters is misleading right now, as it states you should use a yaml list to specify the query parameters you could use. By following the current documentation, GGK simply breaks.

Also, looks like there are leftovers from conflict resolving on the _index.md file currently.
