Remove maps from other chains

[karynemayer]

Overview

We should remove the map because its hardcoded for telos network, showing only the block producers for Telos. Also, other chains don't necessarily want it a map.

Acceptance Criteria

• Include a configuration to a chain to define if the map should appear or not
• Set the configuration to false for every chain except telos and telos testnet.

@karynemayer So this would be an item that needs to be made configurable?

We already have the flag for map display on the chain config. On #747 I turned off the map for the other networks.
