[webauthn] 14.6.3. Privacy leak via credential IDs (#1311)

maxhata has just created a new issue for https://github.com/w3c/webauthn:

== 14.6.3. Privacy leak via credential IDs ==
> This privacy consideration applies to Relying Parties supporting single-factor authentication with non-resident credentials.

This should apply not only to non-resident credentials but also resident credentials if credentialIds are sent. Sending credentialIds in an allowCredentials is a legitimate flow for authentication. Thus, I suggest to change "with non-resident credentials" to something like "when sending an allowCredentials with credentialIds."
