Update Android Keystore attestation verification

[MasterKale]

Describe the issue

Google has been gearing up to replace SafetyNet attestation with Keystore-based attestation:

After playing around with the Chrome origin trial mentioned in the link above I've realized that these attestation statements have changed a bit since ~2020 when I first implemented "android-key" attestation statement verification against FIDO Conformance. I generated a newer "android-key" attestation statement using a Pixel 8a; I should use it to update verification here as I did in py_webauthn in duo-labs/py_webauthn#240.
