stopping colima with launchctl unload path/to/colima.launchd.plist doesn't stop colima

### Description

If you start colima via launchd, it will not stop when launchd unloads the service and sends it a SIGTERM.

colima is started with `/usr/local/opt/colima/bin/colima start -f` when run by launchd, so it is in the foreground to receive the SIGTERM, but it doesn't shut down.

### Version

colima version 0.8.1
git commit: 96598cc5b64e5e9e1e64891642b91edc8ac49d16
limactl version 1.2.0

### Reproduction Steps
