docs: Cloud Deployment Azure

[Jayclifford345]

What this PR does / why we need it:
Continuation of the cloud deployment guides. This teaches the user how to deploy Loki on Azure using the helm. Including:

• Azure Setup
• Helm values config
• Testing
  I have also added some opinionated recommendations to the helm index page for review aswell.

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
• 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

[Docs team] One thing I noticed, there's a lot of bolding in this PR. Try to use bold sparingly, because if you use it too much, it starts to lose its emphasis.
