Fixed the issue causing PrivacyInfo collisions when using Cocoapods

[robert-smartbear]

Goal

Installing Bugsnag using Cocoapods was causing file collisions if the app had its own PrivacyInfo file

Design

Avoid the collisions by using resource_bundles instead of resources

Changeset

Replaces resources with resource_bundles in the podspec

Testing

Manual testing on an example app
