Is not better use standard struct for sn config instead jq and script to create it?

Is not better use standard struct for sn config instead jq and script to create it?

I'm literally just filtering the output down. I think it would be better to not have the flag on config gen and to make the setup-node work with the visor config.

the fields are the same for setup-node as for the visor, but there are extra ones in the visor config.

The script library isn't using any external dependencies here. It uses go-jq which I quite like.

This was just supposed to be a simple and quick fix. It does work, but we can put more thought later into changing this to be different or making setup-node able to use the visor's config.
