Update README based on new exporter format and monitoring dependency

Update documents within docs/ folder to reflect the new update of cluster-auditor no longer pushing logs to an ECK logging stack but being scraped by Prometheus and Visualized within Grafana.

Update description: in chart/Chart.yaml to something more descriptive for cluster-auditor.

Utilize the norwoodj/helm-docs image from docker (more info) and the go template in gluon/docs to generate a new README for the cluster-auditor package. Follow instructions in the Gluon Document https://repo1.dso.mil/platform-one/big-bang/apps/library-charts/gluon/-/blob/master/docs/bb-package-readme.md .

AC:

• Update description: in chart/Chart.yaml to something more descriptive for the application
• README Renders correctly
• Links are correct
• Docs updated to reference Prom/Grafana instead of ECK
