📙 Parse.Cloud.run needs example

[jaysonng]

Link to section:
https://parseplatform.org/Parse-SDK-JS/api/master/Parse.Cloud.html#.run

What is the issue?
There is no example or description of how to use the data and options parameters of the function.

Can you propose a solution?
A simple example of how options parameter could be used and a bit of explanation like so and link to javascript documentation section on Context if I understood it correctly should do the trick.
