When trying to upload to a Swift Registry using the swift package-registry publish command, the operation fails due to the missing _Pods.xcodeproj.
E.g.
swift package-registry publish <scope>.cloudinary-cloudinary_ios 5.1.0 \
--url https://packages.acme.com/artifactory/api/swift/swift-local \
--scratch-directory $(mktemp -d)
Error: /Users/alberto.debortoli/src/cloudinary_ios/_Pods.xcodeproj doesn't exist in file system
