No PrivacyInfo.xcprivacy as of v4.2.2

[viviyang77]

Hey there,

After upgrading the Mixpanel-swift SDK to 4.2.2 (via Cocoapods),
the PrivacyInfo.xcprivacy file is still missing.

Please refer to the screenshot attached.

Would you be releasing an update soon?
Thank you.

v4.2.3 is released with PrivacyInfo.xcprivacy as a resource in the .podspec, Package.swift and Copy Bundle Resources build phase for all targets: #636
