MagTag Google Sheets URL redirect fails

[anecdata]

There's an issue in https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/MagTag_Google_Sheets/weekly_planner/code.py that's been transferred to Requests: https://github.com/adafruit/Adafruit_CircuitPython_Requests/issues/103

I believe the issue is due to a required redirect to access the spreadsheet. This must have behaved differently in the past, but now the redirect is a 307 temporary redirect to a different host (subdomain.domain). Requests I believe only handles redirects within the same host.

While waiting for a Requests change, maybe there's an alternate way to serve the spreadsheet that won't encounter the issue, and gets the guide working again.

Update: after more testing, turns out redirects to other domains are handled fine. The error arises from some other cause (unknown) - see the issue linked for more discussion.
