feat: relaunch on SIGUSR2 (#4979)
This is because Node uses SIGUSR1 to enable the debug listener so even if you just want to restart code-server you end up enabling the debug listener as well. Opted to leave the SIGUSR1 handler in to avoid breaking existing workflows even though it does mean even if you only want to enable the debug listener you will end up restarting code-server as well. We could consider removing it after a transition phase.
