error running simpletest on Pi 5

[FoamyGuy]

Running under Blinka on a Pi 5 is resulting in this error:

$ python sen6x_simpletest.py 
  File "Adafruit_CircuitPython_SEN6x/examples/sen6x_simpletest.py", line 55
    f"Temperature: {data["temperature"]:.1f}°C"
                          ^^^^^^^^^^^
SyntaxError: f-string: unmatched '['

I think maybe one of the sets of quotes needs to either be switched single quotes, or else maybe escape slashes could be used. I will try to fix and submit a PR with resolution once found.
