Dockerfile.dev doesn't trigger as a Dockerfile icon

[erwanriou]

currently using this library since i migrate from atom to vscode (sad about atom deprecation). This is for me the most beautiful library for icons, specifically in colorless. There i have a small issue i couldn't figure out how to fix:

As you can see, the library recognize the Dockerfile but doesn't recognize the Dockerfile.production Could we implement a regex pattern so it reconize all the Dockerfile.xxx extensions as Dockerfile?
