Use newer gdb startup message

The debugging documentation showcased a very old example of the message you see
when starting gdb. This commit updates the example message to the way it looks
in a newer version of gdb (v10.1.90).

Testing Done:
Ran `dev-server.sh` and verified content looked as intended.
