docs: Deploy Loki Helm on AWS guide

[Jayclifford345]

This is the successor PR to the SSD PR #14327 After an internal discussion, it was decided to focus deployment guides for helm on either Monolithic or distributed (microservice mode). The Loki team felt more comfortable supporting both of these deployment styles since its closer to what we deploy internally.

This PR is part of a large redesign to improve the helm documentation of Loki.
