Issue Description:

There appears to be a bug that is preventing the retrieval of the `creationDate` of a file when running on Windows. Assuming `zoo.txt` exists, the following is a minimal-ish reproduction of the issue. Given this code:

import Foundation

let workingDirectoryUrl = URL(fileURLWithPath: Bundle.main.resourcePath!)
let fileUrl = URL(fileURLWithPath: "zoo.txt", relativeTo: workingDirectoryUrl)

let fileAttributes = try! fileUrl.resourceValues(forKeys: [.nameKey, .creationDateKey])

let formatter = DateFormatter()
formatter.dateStyle = .short
formatter.timeStyle = .medium

let formattedName = fileAttributes.name ?? "unknown name"
let formattedDate = fileAttributes.creationDate.map { formatter.string(from: $0) }
    ?? "unknown date"

print("Found \(formattedName), created \(formattedDate)")

The output is `Found zoo.txt, created unknown date`.

Simply changing `creationDateKey` and `creationDate` to `contentModificationDateKey` and `contentModificationDate`, respectively, will yield an actual date.

@spevans - this may partially be the result of your work to use statx on Linux. The change in 692e914 dropped the else path.
