fix: pass predefined acl as destinationPredefinedAcl to qs

[AVaksman]

• Tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary)

Currently optional param predefinedAcl in file#copy is not utilized properly.
As per docs API expects [destinationPredefinedAcl](https://cloud.google.com/storage/docs/json_api/v1/objects/rewrite) as part of the qs (not Json).
