Switch GEORADIUS example arg ordering to match commands.json

commands.json specifies WITHCOORD comes before WITHDIST: https://github.com/redis/redis-doc/blob/8fa5ba577f3f9a90f55027c5a0d83bec8271ad27/commands.json#L1319-L1334

@itamarhaber you are right it's not strictly necessary - but my use case is generating test cases for a strongly-typed client from docs examples, so it's a nice-to-have. My hope was that it at least does no harm, and it encourages consistency in a minor way.
