Updated stop.sh script to use the /admin/stop API endpoint if an apikey.txt file is available.

This brings the behaviour closer to the old version so should hopefully reduce the amount of newly introduced issues. If an API key is unavailable, it will fall back to using `kill -15 $pid` (i.e. a SIGTERM).
