fix: hide hook name

[J0]

What kind of change does this PR introduce?

The HookName is generated from the Postgres URI and used internally to invoke the hook.

Context: #1734 (comment)

Since it's for internal use, we don't expose it similar to what we do with encryption key and other similar fields.

This is fine since we don't marshal the extensibility point.

Testing setup

We don't marshal the struct so it should be fine but for additional sanity check ran this locally:

GOTRUE_HOOK_CUSTOM_ACCESS_TOKEN_ENABLED="true"
GOTRUE_HOOK_CUSTOM_ACCESS_TOKEN_URI="pg-functions://postgres/public/custom_access_token_hook"

create or replace function public.custom_access_token_hook(event jsonb)
returns jsonb
language plpgsql
as $$
  declare
    claims jsonb;
  begin
   

    -- Proceed only if the user is an admin
      claims := event->'claims';

      -- Check if 'user_metadata' exists in claims
      if jsonb_typeof(claims->'user_metadata') is null then
        -- If 'user_metadata' does not exist, create an empty object
        claims := jsonb_set(claims, '{user_metadata}', '{}');
      end if;

      -- Set a claim of 'admin'
      claims := jsonb_set(claims, '{user_metadata, admin}', 'true');

      -- Update the 'claims' object in the original event
      event := jsonb_set(event, '{claims}', claims);

    -- Return the modified or original event
    return event;
  end;
$$;

grant execute
  on function public.custom_access_token_hook
  to supabase_auth_admin;

revoke execute
  on function public.custom_access_token_hook
  from authenticated, anon, public;

grant usage on schema public to supabase_auth_admin;
