YubiKey Manager GUI error

Overview:

When using a "Security Key by Yubico" hardware device, the YubiKey Manager
"ykman fido info" command fails with an error message.

Steps to Reproduce:

1) Install the yubikey-manager package if it is not already installed.
2) Insert a "Security Key by Yubico" device into a USB port.
3) From a terminal, run the "ykman fido info" command.

Actual results:
The ykman application exits with an error message:

  Error: Failed to load FIDO 2 Application.

Expected Results:

The ykman application should display a message about the device PIN. For
example, "PIN is set, with 8 tries left."

Additional Information:

1) When running "ykman -l DEBUG fido info", a traceback is displayed with a
ValueError message:

    raise ValueError("%r is not a valid %s" % (value, cls.__name__))
ValueError: 7 is not a valid KEY

2) The ykman-gui application, from the yubikey-manager-qt package, also
displays an error message after clicking on Applications > FIDO2. See attached
error screenshot.

3) A workaround for the issue is to use python-fido2 0.6.0 or 0.7.3 (available
from https://github.com/Yubico/python-fido2/releases) instead of the
python3-fido2 0.5.0-1.23 package. See attached workaround screenshot.

4) The issue does not occur with a "YubiKey 5 Nano" device.
