Bumps Auth0.Android from 3.21.1 to 3.21.2.

In 3.21.1, when a user presented an unrecognized biometric on a SecureCredentialsManager prompt and then authenticated successfully (for example with the device credential fallback), Auth0.Android delivered two results for one getCredentials() / getApiCredentials() call: a BIOMETRICS_INVALID_USER failure first, then the success. The bridge settles a promise on the first result, so the app saw a failure and the credentials from the successful authentication were dropped. 3.21.2 stops reporting an unrecognized biometric as a final failure (auth0/Auth0.Android#1098, fixing auth0/Auth0.Android#1095).

No bridge code changes. I checked that the module resolves com.auth0.android:auth0:3.21.2 and compiles against it; I haven't run the biometric prompt on a device.
