Add all node types in admin api doc

add all node type in this doc: https://docs.authgear.com/apis/admin-api/node-id

In Admin API, the node id can be used for globally identify an object. It's always in base64url encoded format of <NODE_TYPE>:<ID>

e.g. VXNlcjo5N2IxYzkyOS04NDJjLTQxNWMtYTdkZi02OTY3ZWZkZGExNjA= can be decoded as User:97b1c929-842c-415c-a7df-6967efdda160 meaning it refers to a "User" object.

@louischan-oursky where can I find the list of node types currently in used? Or we need to get them by trial and error from the API?

You can find it in the schema. Technically speaking, the list of node types means the list of types implementing the Node interface. The playground should be the easiest way to do this.
