[w3c/screen-orientation] Steps for updating orientation information are misleading (#100)

In chapter 4.1, steps for updating orientation information refer to a document in several places. Other parts of spec refer to document object as well.

It is misleading, since the ScreenOrientation is part of Screen interface, not the document. Screen orientation may affect document orientation (rendering), not vice-versa. Also, screen orientation can be locked from API (or on platform level), document interface does not have API to lock / unlock it’s orientation.

Following statements imply that document has orientation information:

> The steps to update the orientation information of a document are as follows:

> Set the document's current orientation angle…

> The decision whether the document's current orientation type should be set to *-primary or *-secondary is up to the user agent.
