Looks like we can't currently land the new tests on Windows because the latest toolchain is a few months old and doesn't have exit test support |

In the new
AttributedStringtransform(updating:)functions, there are a variety ofpreconditions that validate the provided input. With XCTest we previously did not have a way to test these preconditions, but now swift-testing has support for exist tests in Swift 6.2. This change migrates the existingAttributedStringIndexTrackingTestssuite from XCTest to swift-testing and adds two additional tests to fully cover the preconditions and expected crashes for this API.
