api-docs: Updated docs for certain endpoint parameters.

In zulip/python-zulip-api#634, certain endpoint parameters
were encoded to make the function callable by passing the arguements,
rather than passing them as a dictionary.

Following api endpoints are affected within the docs:

POST update_presence
GET get_members
PATCH mute_topic
POST render_message
POST create_user
POST set_typing_status
