Docker project setup and build

[lerignoux]

Hello

I usually setup build environments in docker container to avoid having to install npm (or similar dev and build packages) locally.
I did a setup to develop on ComfyUI-frontend with a simple Dockerfile and docker-compose.

Do you think it would be useful to make a merge request with it and it's addition to the Readme ?
Or do you prefer to keep a local npm environment for this project ?

Regards
