[webauthn] new commits pushed by equalsJeffH

The following commits were just pushed by equalsJeffH to https://github.com/w3c/webauthn:

* Add note about decoding U2F keyhandles. (#1272)

* Add note about decoding U2F keyhandles.

U2F key handles need to be base64url decoded before being used as
ArrayBuffers in WebAuthn calls. This isn't completely obvious so this
change adds a clarification to the appid and appidExclude extensions.

* Address Jeff's comments by linking to [=base64url encoding=]
