After updating mozilla-central (to cset 8620f13a9748) today, `mach configure` fails with python 3.9, but succeeds with /usr/local/Cellar/python@3.8/3.8.12_1/bin/python3.8 mach configure`. I'm running Homebrew's python@3.9.10 on macOS 11.6.4. Note that I ran `mach bootstrap` with python 3.8 due to `mach bootstrap` bug 1759322 with python 3.9, in case that matters.

I get the following error message when running `mach configure`, even after deleting my entire ~/.mozbuild directory and local objdir:

```
ImportError: cannot import name 'readPlist' from 'plistlib' (/usr/local/Cellar/python@3.9/3.9.10/Frameworks/Python.framework/Versions/3.9/lib/python3.9/plistlib.py)
