Missed docs for *-bundle images

[davidyuk]

Initially, I was writing this about not working devmode server in master-bundle, but seems it was fixed while I was writing this, the latest master-bundle works fine. Other issues I have:

Devmove plugin is included into *-bundle images since #3725. But I can't find any documentation regarding these images.

Another confusing part is that 3313 port is not mentioned in Dockerfile's EXPOSE section https://hub.docker.com/layers/aeternity/aeternity/master-bundle/images/sha256-d8a1704fc159c2b1aaa388b36e59dd7d1fee9f2810ce7a916be2f2e1bb490165?context=explore
I find out that it is not required, but still

We use single Dockerfile for now so we can't have an EXPOSE of the port. Documentation can be added indeed in the docker section of the docs.
