[gql] Add boolean endpoint for whether a location has integrated docs (#29216)

## Summary

Adds a boolean `hasLocationDocs` endpoint which returns whether a
location has integrated docs. Nested under `GrapheneRepository`, along
with moving the endpoint from #29167

## How I Tested These Changes

Update unit test.
