`itemReplacementDirectoryName` has forgotten the closing bracket when `attempt` is greater than 0

Description

itemReplacementDirectoryName has forgotten the closing bracket when attempt is greater than 0. It is a local function in FileManager.url(for:in:appropriateFor:create:).

Steps to reproduce

$ rmdir /tmp/TemporaryItems/*
$ swift repl
Welcome to Swift version 6.0.1 (swift-6.0.1-RELEASE).
Type :help for assistance.
  1> import Foundation
  2> try FileManager.default.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: URL(filePath: "/tmp"), create: false).path 
$R0: String = "/tmp/TemporaryItems/(A Document Being Saved By replswift)"
  3> try FileManager.default.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: URL(filePath: "/tmp"), create: false).path 
$R1: String = "/tmp/TemporaryItems/(A Document Being Saved By replswift 2"
  4> try FileManager.default.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: URL(filePath: "/tmp"), create: false).path 
$R2: String = "/tmp/TemporaryItems/(A Document Being Saved By replswift 3"
  5> try FileManager.default.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: URL(filePath: "/tmp"), create: false).path 
$R3: String = "/tmp/TemporaryItems/(A Document Being Saved By replswift 4"
  6> ^D

As you can see, it outputted:

• "/tmp/TemporaryItems/(A Document Being Saved By replswift)"
• "/tmp/TemporaryItems/(A Document Being Saved By replswift 2"
• "/tmp/TemporaryItems/(A Document Being Saved By replswift 3"
• "/tmp/TemporaryItems/(A Document Being Saved By replswift 4"
• ...

Expected behavior

I think it should output:

• "/tmp/TemporaryItems/(A Document Being Saved By replswift)"
• "/tmp/TemporaryItems/(A Document Being Saved By replswift 2)"
• "/tmp/TemporaryItems/(A Document Being Saved By replswift 3)"
• "/tmp/TemporaryItems/(A Document Being Saved By replswift 4)"
• ...
