Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/ce1dbb2de90624ef7594b144c1a0f0ba2e3b226b (Update check_annotations.py.).

This shouldn't be related, as the changelist only modifies a script that is used on a linux_chromium_rel_ng test, and the changed functions are not effectively in use now.
