docs: Added Simple Scalable Deployment guide for AWS

[Jayclifford345]

This PR adds a guide to deploying the official Loki helm to AWS in Simple Scalable. It is worth noting that there are lot of AWS specific commands within this guide. This is hard to escape due to the nature of how Loki is deployed to AWS. I have added cavitates throughout the guide to help reduce the support burden on AWS-specific questions.

I am open to removing these sections but feel the guide would be insufficient for a user attempting to deploy Loki on AWS.

Checklist

• Reviewed the CONTRIBUTING.md guide (required)
• Documentation added
• Tests updated
• Title matches the required conventional commits format, see here
  • Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
• Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
• For Helm chart changes bump the Helm chart version in production/helm/loki/Chart.yaml and update production/helm/loki/CHANGELOG.md and production/helm/loki/README.md. Example PR
• If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR

Hey @tomglenn, @poyzannur, @trevorwhitney thank you ever so much for the technical reviews. That should be all of your suggestions added. I shall let @JStickler give it the full docs review next and see where we are at. Then I can start filming the video

great PR. Some minor things found but overall a massive improvement/contribution to what's there

[jenshor]

Great improvement on the docs. Once I found this PR, I was quickly able to deploy Loki in SimpleScalable mode 👍🏻

Hi all, after an internal discussion I am closing this PR and opened this one instead #14517 . This was after an internal discussion that we felt it was better to focus the deployment guide on distributed (microservice) and Monolithic deployments of the Loki helm. Let me know what you think of the changes in the other PR if you get chance!
