create.sh executes helm

Summary

The create.sh helper script executes helm create myapp on line 30, rather than sending that as a string to ${fullpath}/helm/README.md. This can be fixed by escaping the backticks.

Steps to reproduce

Execute create.sh. I found the issue on Ubuntu 18.04.

What is the current bug behavior?

The command tries to execute and it will fail if helm is not installed. If helm is installed it will create a top-level directory called myapp.

What is the expected correct behavior?

The text should be put into the helm README and not be executed.
