Docs/admin-guide/mm/damon/start: add --target_pid to DAMOS example command

The example command doesn't work [1] on the latest DAMON user-space tool,
since --damos_action option is updated to receive multiple arguments, and
hence cannot know if the final argument is for deductible monitoring
target or an argument for --damos_action option.  Add --target_pid option
to let damo understand it is for target pid.
