chrome.gcm documentation contains excessively long union types

[dotproto]

Describe the bug

The type signature for the chrome.gcm.register method's objections objet's senderIds property is a union of arrays of strings of various lengths (many of which are of identical length). The type ends up being more than one screen worth of content on a 1920x1080 display.

To Reproduce
Steps to reproduce the behavior:

1. Visit https://developer.chrome.com/docs/extensions/reference/gcm/#method-register

Observe the long type signature.

Expected behavior
The type signature should be meaningful to the average visitor.

Omg, wow, this is disgusting 😄.

@dotproto I'm thinking it just being string[] would be sufficient?

That's my first thought as well. The docs state that this property "should contain at least one and no more than 100 sender IDs." I assume the current typings are coming from an IDL file that explicitly declares each length from 1 to 100.

We may need some special casing in the types project to collapse this kind of variable length array with a max length into just string[] as you suggested.
