Add Privacy Manifest

[mvn-toantruong-dn]

Hello, I am an employee of Monstarlab company. I have a question about the Privacy Manifest.

At WWDC23 Apple is requiring all api calls that fall under this ruleset https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_use_of_required_reason_api#4278394 be added to a privacy manifest file. Does SwiftyUserDefaults need to include this manifest? Please let me know about your upcoming plans to apply the privacy manifest.

Thank you!!!

I can't find the PrivacyInfo file in the master branch, and I can't find the file in the pod update library. I don't think it has been added.
