Add Privacy Manifest

[sagarthecoder]

Apple says "Starting May 1, 2024: You'll need to include approved reasons for the listed APIs used by your app's code to upload a new or updated app to App Store Connect."

Please add privacy policy otherwise we couldn't use this library.

@sagarthecoder I've added the privacy manifest in #709.

Since this SDK doesn't collect any user data, is it correct to leave the file empty like this?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict/>
</plist>

This SDK doesn't use any API from the list, so no need for Privacy Manifest.
