Clearer error messages for supabase link

Is your feature request related to a problem? Please describe.

When linking projects for local development with supabase link, you get the following error for the following cases

• Your host isn't in the IP allow list.
• Your host is in the IP allow list, but you've provided an invalid password

failed to connect to postgres: failed to connect to `host=aws-0-us-east-1.pooler.supabase.com user=postgres.vizglusznacdygtioulv database=postgres`: server error (FATAL: SSL connection is required (SQLSTATE XX000))

Searches on this error send you down incorrect (and time-consuming) rabbit holes to threads like these

Describe the solution you'd like

Finer-grained error messages. When I switch to trying to connect with psql, I get the following errors, so I suspect we can provide them in the error output from supabase link
