Docs: Outdated `client.authenticate()` Response in V2 Documentation

[hjaber]

In the V2 docs, I believe the old response & type for client.authenticate() is being displayed while the playground uses the newer V2 response.

The authentication docs state the response should be:

{
  "credentialId": "3924HhJdJMy_svnUowT8eoXrOOO6NLP8SK85q2RPxdU",
  "authenticatorData": "SZYN5YgOjGh0NBcPZHZgW4_krrmihjLHmVzzuoMdl2MFAAAAAQ==",
  "clientData": "eyJ0eXBlIjoid2ViYXV0aG4uZ2V0IiwiY2hhbGxlbmdlIjoiNTY1MzViMTMtNWQ5My00MTk0LWEyODItZjIzNGMxYzI0NTAwIiwib3JpZ2luIjoiaHR0cDovL2xvY2FsaG9zdDo4MDgwIiwiY3Jvc3NPcmlnaW4iOmZhbHNlLCJvdGhlcl9rZXlzX2Nhbl9iZV9hZGRlZF9oZXJlIjoiZG8gbm90IGNvbXBhcmUgY2xpZW50RGF0YUpTT04gYWdhaW5zdCBhIHRlbXBsYXRlLiBTZWUgaHR0cHM6Ly9nb28uZ2wveWFiUGV4In0=",
  "signature": "MEUCIAqtFVRrn7q9HvJCAsOhE3oKJ-Hb4ISfjABu4lH70MKSAiEA666slmop_oCbmNZdc-QemTv2Rq4g_D7UvIhWT_vVp8M="
}

but the playground shows the new V2 correct response:

{
  "clientExtensionResults": {},
  "id": "XZg7VBiVGFZzHmC4OrTXNQ",
  "rawId": "XZg7VBiVGFZzHmC4OrTXNQ==",
  "type": "public-key",
  "authenticatorAttachment": "platform",
  "response": {
    "authenticatorData": "T7IIVvJKaufa_CeBCQrIR3rm4r0HJmAjbMYUxvt8LqAdAAAAAA==",
    "clientDataJSON": "eyJ0eXBlIjoid2ViYXV0aG4uZ2V0IiwiY2hhbGxlbmdlIjoiYmYxOWQ3ZjktZjk3ZS00NjEyLTg0MjYtNDYwZTExZmExOTBmIiwib3JpZ2luIjoiaHR0cHM6Ly93ZWJhdXRobi5wYXNzd29yZGxlc3MuaWQiLCJjcm9zc09yaWdpbiI6ZmFsc2V9",
    "signature": "MEYCIQC1FA7k7j7zf50ar9STzkanna16IkZdIYHwLNeWYWxCRwIhAITEOUcqnMC9_EHmjRxzoq3K-Titr3nWSZKY9n1yC_cL",
    "userHandle": "ZDUzMGYxMGQtZmI2ZS00ZjdkLTgzMTMtZWQ5N2QzYTU2ZDQ4"
  }
}

I discovered this because credentialId is changed to id from the response of client.authenticate() which was a breaking change

// obtained from database by looking up `authentication.credentialId`

interface AuthenticationResponseJSON {
    id: Base64URLString;
    rawId: Base64URLString;
    response: AuthenticatorAssertionResponseJSON;
    authenticatorAttachment?: AuthenticatorAttachment;
    clientExtensionResults: AuthenticationExtensionsClientOutputs;
    type: PublicKeyCredentialType;
}

I started a PR but I wasn't able to completely to update the docs and I wasn't confident that I correctly found an issue rather than making a mistake on my end.

Thanks for reporting, I updated the docs for that part. 👍 ...There might still be a few outdated docs paragraphs lurking around. 😖
