I have a designer and users who are familiar with the Twig template format and know little to no PHP so I include a few Twig templates in my extensions. I would like the designer or user to be able to use overrides on files that use an extension other than .php

In the com_templates component could we add another few types of extensions?

the line to change is com_templates/models/template.php#L787

I think some other extensions that might be helpful to include are:

• .twig.html
• .html.twig
• .blade.html
• .html.blade

Maybe we could add allowed extensions in the system configuration for com_templates under the Supported File Formats section.
