fix(drizzle-kit): silence raw NOTICE objects from postgres-js driver

[SAY-5]

When the postgres-js driver path runs internal idempotent statements like CREATE SCHEMA IF NOT EXISTS drizzle and CREATE TABLE IF NOT EXISTS drizzle.__drizzle_migrations, PostgreSQL emits NOTICE messages on subsequent runs. postgres.js's default onnotice handler prints the raw NOTICE objects to stdout, which dumps unstructured payloads on top of drizzle-kit's own output during drizzle-kit migrate.

Pass an empty onnotice to suppress this. Errors are still surfaced through the normal query rejection path, so this is purely cosmetic output cleanup.

Before:

{
  severity_local: 'NOTICE',
  severity: 'NOTICE',
  code: '42P06',
  message: 'schema "drizzle" already exists, skipping',
  file: 'schemacmds.c',
  line: '132',
  routine: 'CreateSchemaCommand'
}
{
  severity_local: 'NOTICE',
  severity: 'NOTICE',
  code: '42P07',
  message: 'relation "__drizzle_migrations" already exists, skipping',
  ...
}

After: clean drizzle-kit output, no raw NOTICE dump.

Closes #5643
