[BUG] file CodeSnippet for a .yaml or .yml file should insert a block that starts with ```yaml or ```yml

[lestephane]

When I use

<!---[CodeSnippet](file=step3/template.yml)-->

The resulting inserted block starts with

| ```

instead of

| ```yml

or

| ```yaml

Not sure which one is correct between yaml and yml. Autocompletion in Intellij only shows yaml
