[bug] Missing field "sensitive" in CredentialAccount

Describe the bug with a clear and concise description of what the bug is.

I'm not sure if it's a GoToSocial bug or overzealous parsing on the side of mastodon-async library which I'm using, but both Mastodon and Akkoma do provide that field.

What's your GoToSocial Version?

6.0.0

      "note":"",
      "fields":[

      ]
   },
   "role":"admin"
}

What you expected to happen?

source should contain a sensitive boolean field as per docs for CredentialAccount.

How to reproduce it?

GET <my_instance.my_domain>/api/v1/accounts/verify_credentials using an authenticated app.

Anything else we need to know?
