Update the CHANGELOG for Crashlytics to better document the changes.

[tejasd]

The SDK contains a new API which was added in #6528.

Since it's a new API, this should be a minor version bump, and not a patch.

Edit: This is an API overload that's backwards compatible and so it's probably OK for it to be a patch release.
