sh / bash / zsh?

I just started using lazydocker, and really like the `E` shortcut.

As far as I can tell, this executes `/bin/sh`. A keypress of the arrow up then produces a `^[[A` (on my system: ubuntu, german/swiss keyboard layout) . I don't know enough about shells to tell where this is coming from exactly...but, executing `/bin/bash` as first command resolves the arrow up problem. I guess that not all containers provide `bash`, so `sh` is the sane default?

Point: I was looking for a configuration option, to tell lazydocker whicht shell to use when pressing `E`. I know I could achieve the same with custom commands, but it would be a keypress more, every time ;-) Also, I might be missing something in the docs...?
