Added extra padding to resources template

This is probably a silly PR.  However, each time I create a new chart
via `helm create`, the instructions to uncomment the resource limits
require adding a couple extra spaces back to the YAML.

This PR simply brings the spacing in-line with the rest of the generated
template.
