Also export type FunctionsResponse from functions-js

[maximilian-hammerl]

What kind of change does this PR introduce?

Also export type FunctionsResponse from functions-js

As the return type of the invoke method of the FunctionsClient class, the FunctionsResponse type is significant if one wants to type the response when calling the invoke method.

What is the current behavior?

Currently, one has to have functions-js as a dependency just for the FunctionsResponse type.
