* Specify token used in /login is not an Access Token
While working through the implementation of /login in Dendrite, it was
confusing what the contents of the token attribute in the login request
body referred to. Initially, I thought it was an access token, which led
to further confusion. This commit explicitly states that the token is a
login token, which is separate from an access token, hopefully reducing
confusion for future readers.
