Rename "posture modes" to "posture types"

[beaufortfrancois]

As the DevicePosture interface has now a member called type, we may want to rename posture modes to "posture types" for consistency.
What do you folks think about it?

interface DevicePosture : EventTarget {
  readonly attribute DevicePostureType type;
  ...
};

I think this was addressed by #65 (thanks @beaufortfrancois for that PR!).

It was not addressed by #65. This issue is about renaming the "posture modes" in https://w3c.github.io/device-posture/#posture-modes to "posture types".

Sorry for being trigger-happy, reopened.

I don't have a strong preference but if we were to be consistent, we should use "modes" in my opinion. Samsung and other folks have been using terms like "tent mode" or "flex mode" and I regularly hear people saying "being used as laptop mode".

I think it should be Type as it's an enum. Would be consistent with Orientation lock spec
