Add installed architecture to telemetry data

[sjberman]

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

Testing: Verified value in logs:

{"level":"debug","ts":"2024-02-21T18:03:03Z","logger":"telemetryExporter","msg":"Exporting telemetry","data":{"ProjectMetadata":{"Name":"NGF","Version":"edge"},"ClusterID":"3b13d5bb-3ccb-4a25-9caf-99d3f9ba89ad","Arch":"arm64","NodeCount":1,"NGFResourceCounts":{"Gateways":1,"GatewayClasses":1,"HTTPRoutes":2,"Secrets":0,"Services":2,"Endpoints":2},"NGFReplicaCount":1}}

Closes #1316
