Fix NGINX example load balancer of a gateway collector deployment

[oCHRISo]

What needs to be changed?

Within the gateway page, the NGINX configuration within NGINX as an "out-of-the-box" load balancer examples section is incorrect. The example highlights three collectors (collector1, collector2, and collector) but within the NGINX configuration, only collector1 and collector2 are upstream. All 3 collectors are required to be in the upstream.

What is the name + path of the page that needs changed?

Path: content/en/docs/collector/deployment/gateway.md
Title: Gateway

Additional context:

I think it should be collector1, collector2 and collector3 right? But beyond that, I agree. Are you willing to create a PR for that (note that we require contributors to sign a CLA)?

Yes that's correct and I'm happy to do a PR to address. Thanks for your reply
