Re: [webauthn] Mark Android SafetyNet attestation as deprecated. (#2155)

> Also, our links to "the steps indicated by the [SafetyNet online documentation](https://developer.android.com/training/safetynet/attestation.html#compat-check-response)" no longer lead to the verification steps, but instead to a page describing the deprecation timeline. Is there some way we can still access the verification steps so that we could inline them into WebAuthn (I'm not sure we should, just wondering if we can)?

As for this, we might have to fall back to consulting existing verification implementations in WebAuthn libraries. For what it's worth, here's mine:

https://github.com/MasterKale/SimpleWebAuthn/blob/dc70416e781c9ab11625ba9afbf092809391874e/packages/server/src/registration/verifications/verifyAttestationAndroidSafetyNet.ts#L15

I'd link to py_webauthn's implementation but it's pretty much the same. I'm sure other libraries can be used to independently verify the logic if we wanted to map it to spec speak.
