Fix comments in Dart template

Remove overly-permissive data file rules from Node template

.gitignore uses `#` for comments, not `//`

These aren't really common patterns in the Node world, and if a Node project includes one of these types as files, they're as likely to want to include them in the project as not (`*.csv` is as likely to be a data source as `*.json`).
