See https://github.com/nodejs/node-v8/actions/runs/6093305552/job/16532764329

I do not have time to fix it until next week.

Backport command is still broken:

$ git node v8 --v8-dir ~/git/chromium/v8/v8 backport 1a3ecc2483b2dba6ab9f7e9f8f4b60dbfef504b7
✔ Update local V8 clone
⠋ V8 commit backport

Exit code: 1
