Proposal: Disable the lstn in command in favor of lstn scan for now

[fntlnz]

It looks like the lstn in command is giving headhaches to some of our users.

Initially we thought about the lstn in command as our main entrypoint for repositories, that command is very interesting to execute because it goes in-depth with the scan by analysing all the transitive dependencies directly.

However to make it working properly we need to complete the work on https://github.com/listendev/erborist.

So I'm proposing to disable lstn in and suggest users to use lstn scan instead.

lstn scan gives the same kind of result of lstn in and takes the same input, the only difference is that it will not directly require all the transitive dependencies to the analysis request.

Once we finish the work on erborist we can re-enable the command and advise users on using it.

What do you all think?
