Support for .template files

[jdesulme]

We have all of our CFTs configured with a .template extension. The docs seem that it's supported but it's actually not. I verified this by changing the extension to .json and it began working although not as good as the VSCode extension. It would help if this plugin supported the .template extension.

Do you use just .template, or do you use .json.template and .yamk.template?

We use the json template for all our CFTs that use the .template extension. In some cases it's possible that it can be interchangeable though.
