spec 'erase' param on /account/deactivate

[richvdh]

matrix-org/matrix-js-sdk#649 added an optional 'erase' boolean to the /account/deactivate API

Note: The description of the auth (Authentication Data) param is unclear.
The session value is not expected in case of deactivation.

The example should be updated by using an actual type (like m.login.password):

{
  "auth": {
    "type": "m.login.password",
    "identifier": {
      "type": "m.id.user",
      "user": "<user_id or user localpart>"
     },
    "password": "<password>"
  },
  "id_server": "example.org",
  "erase": true
}

or

{
  "auth": {
    "type": "m.login.password",
    "user": "<userId>",
    "password": "<password>"
  },
  "id_server": "example.org",
  "erase": true
}

matrix-org/matrix-spec-proposals#2438 seems like it would fix this
