Update indent in jshint template

All the files copied from the templates folder have 2 spaces of indentation, but currently the jshintrc file that is copied indicates indentation of 4 spaces causing linting errors.

<del>This changes the indentation from `4` to `2`.</del>

**Updated:** This change changes the indentation in the template files to 4 spaces to match the `jshintrc` file.
