Update README.md (#1024)

Minor grammar and consistency edits.

Note: There is inconsistent capitalization of Promtail/promtail. If you let me know which is correct, then I will update this topic as well as the Grafana Style Guide (in progress).

 Currently there are five ways to try out Loki, in order from easier to hardest:
 
-- [Using our free hosted demo](#free-hosted-demo)
-- [Running it locally with Docker](#run-locally-using-docker)
-- [Using Helm to deploy on Kubernetes](#using-helm-to-deploy-on-kubernetes)
