Fix rendering of chrome.gcm senderIds type.

[oliverdunk]

Overview

Improves rendering of the chrome.gcm senderIds type in the chrome.gcm.register function.

Old	New

Thought Process

When generating the chrome.gcm docs, we were previously seeing the following in the gcm.json spec:

{
  "name": "senderIds",
  "type": "array",
  "items": {
    "type": "string",
    "minLength": 1
  },
  "minItems": 1,
  "maxItems": 100,
},

And generating a union of all possible array lengths.

While it would be nice to have proper rendering for this in the future (e.g a min and max length tag) this PR implements a temporary solution where we simply collapse the type to X[] when we see more than 10 (an arbitrary but reasonable sound number) possible types. This seems reasonable since chrome.gcm is currently the only API with this problem (I checked) and the comments already explain the limit in detail.
