Node 20 is probably going to be more secure, although I have not tried to build it myself so not sure if it would work. I think if the upgrade is already going to happen may be better to do that. Also may make sense to try and have separate build and run steps in the Dockerfile

@salmgazer : Are you currently running kutt with these changes?

I was wondering why the added python.

Rest looks good.
