CLI: Add --raw option to verdi code list

[sphuber]

Fixes #5762

If the flag is specified, the output will only print the projected data without decorative table graphics or additional information.

Cheers @sphuber - having a "raw" output for these commands is certainly useful; since we are adding this now, however, it might make sense to think a little bit about the approach.

Instead of adding an option specifically for hiding output that is meant for interactive use, I would suggest instead to add a generic --output-format option that defaults to, say, interactive, but can also be set to tabular, etc. (see e.g. the example of the kubectl cli).

Our tabular format is still rather aiida-specific and requires the user to parse it. We therefore may eventually want to add other formats - e.g. JSON is very easy to further process with cli tools like jq.

Good point, but we should probably open another feature request for this. The --raw option is already omnipresent in the CLI, here we are just adding it for verdi code list. Don't think we should introduce a new concept for this one-off feature request.

Ok, in that case fine to add it here as well for the moment
