Changelog: Move collapsable to Shared View props
I'm researching why `collapsable` isn't passed to Fabric UIManager in production build, I discovered that collapsable was Android only prop but in Fabric we use it in iOS as well.
This doesn't fix the collapsable not being passed through but I think this makes code semantically correct.
