[bug#49425] [PATCH] guix-install.sh: Prompt for configuring substitutes discovery.

Hi,

Indentation is off, compared to the other functions.

Should the message say a bit more, similar to that in (gnu installer
newt substitutes)?

Otherwise LGTM!

Note that someone running “yes | ./guix-install.sh” will now have
substitutes enabled (whereas it’s off by default in
<guix-configuration>).  I suppose that’s fine though.

Thanks,
Ludo’.
