Does this work for you?

It throws errors for me around sockets, zip & gd.

To fix it I had to upgrade the Dockerfile to apt-get install:

    libzip-dev
    libfreetype6-dev
    libjpeg62-turbo-dev
    libpng-dev

Configure GD with something like:

    && docker-php-ext-configure gd --with-png-dir=/usr/include/ \
        --with-jpeg-dir=/usr/include/ \
        --with-freetype-dir=/usr/include/ \

And install sockets & gd extensions by adding them to the docker-php-ext-install

From there it builds fine and runs Mautic.

@madmath03 with 7.4 support coming with the 3.2 release, maybe we can look to expand this (or create a new PR) so that Docker will also support it?
