[Ankur1493]

There was an trailing comma, which was causing errors while running docker-compose up command, so this is just to remove it

@Ankur1493 This doesn't fix the docker-compose up issue though

[developerTested]

issue is package node-gyp which depend on Python which does not exists hence eror

add these to docker file before running npm install

# Build dependencies
RUN apk add make gcc g++ python3

# install node packages
