Add FFmpeg to the Activepieces docker image...

I want to create an FFmpeg piece but right now, it means creating a custom Dockerfile to add FFmpeg to the Activepieces container. I know there are tradeoffs due to keeping the image small, but adding FFmpeg would be an extremely valuable addition to the platform. If FFmpeg can be added, I will create and contribute an FFmpeg pieces with a general-purpose action that essentially allows a user to mimic the FFmpeg command line.

(P.S. I’m open to suggestions for alternate ways to integrate FFmpeg into a flow.)
