[MBL-1358] Add Privacy Manifest File

[scottkicks]

… type and reason

📲 What

Creates a new Privacy Manifest file and includes the missing reasons for our use of the called out NSPrivacyAccessedAPICategory types

🤔 Why

From Apple:

Missing API declaration - Your app’s code in the “Kickstarter” file references one or more APIs that require reasons, including the following API categories: 
- NSPrivacyAccessedAPICategoryUserDefaults
- NSPrivacyAccessedAPICategoryFileTimestamp

We need to provide appropriate reasoning for these or else we won't be accepted in the App Store.

🛠 How

• Creates a new PrivacyInfo.xcprivacy following Apple's docs
• Adds the NSPrivacyAccessedAPICategoryUserDefaults type and reason following these apple docs

We aren't using the NSPrivacyAccessedAPICategoryFileTimestamp type internally. Rather, it looks like Kingfisher does. Specifically, they use: modificationDate, creationDate, contentModificationDateKey, and creationDateKey

• I think the solution here is to update Kingfisher to >= 7.10.0 (the version where they updated their privacy manifest) instead of updating our manifest. We're reaching out to Apple to hopefully get some clarity on that. It might not be a big deal to update the version anyway.

LGTM. Makes sense, we just use defaults for our own local storage.
