Brief overview of PR changes/additions

If I didn't install luarocks inspect and did lapis migrate I got:

Motivation for adding to package repo

it won't work without it.

But another question is. Is it even needed? After checking config.lua it doesn't seem to be used by anything.

It helps with debugging, it's basically display()

Can you add it to the Dockerfile as well?

I didn't test if it works but it seems to be already present in the dockerfile. https://github.com/Mudlet/mudlet-package-repo/blob/b5ffc2d68c97eb969324da01c1663b8cfd53562c/Dockerfile#L19
