Production code is using debug endpoints

[KaloyanTanev]

In the validators file, there is a call to fetch all validators from beacon state if neither PKs or indices are supplied. Then this function calls the BeaconState function, which sends a request to debug endpoint.

This shouldn't be used in production code, instead the proper v1 endpoint for this should be put into use.

Having debug in the endpoint is a misnomer nowadays, this namespace is enabled by default in all major beacon node implementations and the only reason that the endpoint wasn't moved to a non-debug namespace was the effort involved in migration.
