Add installed architecture to telemetry data

Problem: As a maintainer of NGF/NIC
I want to record the architecture used (ARM, x86, etc) from all participating NGF installations
So that I can ensure used architectures are tested.

Solution: Use the golang runtime library to extract the architecture
