Dockerized chromium support

It would be awesome if we could use a docker container for the chromium instance so that it can be kept up-to-date more easily and the dependencies won't cause issues on the server.

Is this already possible or could support be added?

Start by inspecting the repository's Chromium launch and dependency setup to see how the browser is currently installed and invoked. Determine whether a Docker container is already supported, then define the required container integration and verify that webpage-to-PDF conversion works without server dependency conflicts.
