Subject: [PATCH] fix: ensure conf.d directory exists for postgres 17
 compatibility

The new postgres image (17.6.1.058) includes an include_dir directive
in postgresql.conf that requires /etc/postgresql-custom/conf.d to exist.

When upgrading from older CLI versions, existing config volumes do not
contain this directory. Docker does not copy image contents when mounting
a volume that already has data, causing postgres to fail with:

  could not open configuration directory /etc/postgresql-custom/conf.d

This fix adds mkdir -p to create the directory before postgres starts,
ensuring backwards compatibility with existing volumes.

Closes supabase/supabase#41012
