Update GreyNoise Community IP Lookup Adapter

# Description
Update the Greynoise Community IP Lookup Adapter per meeting with Greynoise

## What
Per meeting with Greynoise, we discovered that we can suppress the 'message' field in the response, as it has no value for the end user, and we should only query valid IPv4 addresses.

Further, we can remove the version from the User Agent.

## Why
These changes were recommended by Greynoise for better user results as well as to reduce queries with IP addresses that not valid (e.g. reserved addresses, IPv6).
