Re: [webauthn] Revisit description of userHandle (#1909)

I realise after writing this that I was originally still looking at an [old definition of step 6 of section 7.2](https://www.w3.org/TR/webauthn-3/#sctn-verifying-assertion) and that under the new definition of that step the userHandle can be used to lookup an account then it is required that the credentialID also be matched to that account, which is ok.

I do have some lingering concerns over allowing the user/client to initiate account lookups based on an injected userHandle, but don't have a concrete reason as to why that's a terrible thing to do just yet.
