pybind/mgr/pg_autoscaler: typo default option scale-up to scale-down

Typo: `scale-up` should be `scale-down` in Module
Option.

This typo doesn't trigger a bug because we create
a key-value of `scale-down` profile in
the function `create_initial()` in `src/mon/KVMonitor.cc`.
This will override whatever is the default option
in pg_autoscaler/module.py when we start the cluster and
the monitor gets created.

The command: `ceph osd pool set autoscale-profile <option>`
is still the primary command to change the autoscale-profiler
after the pool is created.
