.recursiveDescription doesn't work properly for SwiftUI views

[severeduck]

Describe the bug
When view hierarchy is created, a Swift UI identifier doesn't get purged. It causes unit test to fail because ids always mismatch. In my case it's

−<_TtGC7SwiftUI14_UIHostingViewGVS_15ModifiedContentVC20SnapshotTestingTests20SnapshotTestingTestsP10$10e77fe206MyViewGVS_19_BackgroundModifierVS_5Color___; frame = (0 0; 500 500); gestureRecognizers = <NSArray>; layer = <CALayer>>

$10e77fe206
$10724fe206

I found the func purgePointers(_ string: String) -> String { but it doesn't seem to be possible to fix it for me without modifying the code inside the library which I would really like to avoid. Creating a new strategy also doesn't seem to help in this scenario.

To Reproduce
swift-snapshot-testing-main 2.zip

You can add the following code inside the func testSwiftUIView_iOS() at the bottom of the function body (or download the zip):

    // ...
    let hostingVC = UIHostingController(rootView: view)
    assertSnapshot(matching: hostingVC.view, as: .recursiveDescription(size: .init(width: 500, height: 500)))

Expected behavior
The test should succeed.

Environment

• swift-snapshot-testing version 1.10.0
• Xcode 14.0.1
• Swift 5.7
• OS: iOS 13, iOS 16 - doesn't really matter
