Event data should accepts json object with expressions not just a single expression as string.

[fjtirado]

Field data on EventRef definition is of type string. However arguments of a FunctionRef are of type object.

What would you like to be added:
Field data should behave as fields arguments.

Why is this needed:
In order to be able to build a json object to be passed as data of the cloud event, as it is currently done for function arguments.

Closing since this is already implemented in the current main branch. SDKs might release alpha versions targeting the upcoming 0.9 version.
