[mediacapture-main] Update onoverconstrained event handler attribute description (align with others)

adam-be has just created a new issue for 
https://github.com/w3c/mediacapture-main:

== Update onoverconstrained event handler attribute description (align
 with others) ==
We have cleaned up the majority of the event handler attribute 
descriptions. We left the one for onoverconstrained since it was a 
moving target.
