Relax Huggingface login requirement during setup (#2046)

* (config) handle huggingface token more gracefully

* (docs) document HuggingFace token requirement for Concepts

* (cli) deprecate the --(no)-interactive CLI flag

It was previously only used to skip the SD weights download, and therefore
the prompt for Huggingface token (the "interactive" part).

Now that we don't need a Huggingface token
to download the SD weights at all, we can replace this flag with
"--skip-sd-weights", to clearly describe its purpose

The `--(no)-interactive` flag still functions the same, but shows a deprecation message

* (cli) fix emergency_model_reconfigure argument parsing

* (config) fix installation issues on systems with non-UTF8 locale
