Empty continuation line

[wmortada]

Docker is showing a warning about the empty continuation line in the Dockerfile:

[WARNING]: Empty continuation line found in:
    RUN curl -sL https://deb.nodesource.com/setup_14.x | bash -   && apt-get update   && apt-get install -y --no-install-recommends   bash-completion   default-mysql-client   git   iproute2   less   libc-client-dev   libicu-dev   libjpeg62-turbo-dev   libkrb5-dev   libmagickwand-dev   libpng-dev   libxml2-dev   libzip-dev   msmtp-mta   nano   nodejs   rsync   sudo   unzip   vim   zip   && rm -r /var/lib/apt/lists/*
[WARNING]: Empty continuation lines will become errors in a future release.

I think we just need to remove the blank line.
