[Web API issue] Episode object has "restriction" property instead of "restrictions"

[apibugsreporting]

According to the API documentation, the episode object may contain a property called "restrictions" (plural), but in fact, this property is "restriction" (singular). See screenshot for an example. This mismatch should be documented. Client applications may crash when trying to access the "restrictions" property of the episode object, since it doesn't exist.
