update frozen libraries main

This should resolve reported issues:

• AttributeError: 'PyPortal' object has no attribute 'root_group' Adafruit_CircuitPython_PyPortal#139
• PyPortal' object has no attribute 'root_group Adafruit_Learning_System_Guides#3055

If we are intending to make any more releases in the 9.2.x line I can submit a PR for that branch too.

Thanks! I almost always update libraries before a release, too.

[dhalbert]

Thanks. I usually also do this before a release.

Since I am conservative I still use 9.2.8. So I would appreciate it if you also merge this to 9.2.x. Even if you don't make a new release, I can just update my 9.2.x branch and keep it in sync with upstream.
