The suggested fix for the protocol composition type is incorrect when enable upcoming feature`ExistentialAny`

[treastrain]

Description
In Swift 5.8, SE-0335 "Introduce existential any" can be enabled by SE-0362 "Piecemeal adoption of upcoming language improvements". In that case, if the existential type is not given the any keyword, it causes a build error.

That build error contains a suggested fix, but it suggests a fix that seems incorrect when using protocol composition types.

Steps to reproduce

1. Create a Swift Package and open it Xcode 14.3.

% mkdir ExistentialAnySample

% cd ExistentialAnySample

% swift package init --type executable
Creating executable package: ExistentialAnySample
Creating Package.swift
Creating .gitignore
Creating Sources/
Creating Sources/main.swift

% xed .

2. Enable upcoming feature ExistentialAny.

// swift-tools-version: 5.8

import PackageDescription

let package = Package(
    name: "ExistentialAnySample",
    targets: [
        .executableTarget(
            name: "ExistentialAnySample",
            path: "Sources",
            swiftSettings: [
                .enableUpcomingFeature("ExistentialAny"),
            ]),
    ]
)

3. Write the following code in main.swift and build it (we will get some errors).

//
//  main.swift
//  ExistentialAnySample
//
//  Created by treastrain on 2023/04/08.
//

class C {}
protocol P {}
protocol Q {}

func f1(_ v: C & P) {} // ❌ Use of protocol 'P' as a type must be written 'any P'

func f2(_ v: P & Q) {} // ❌ Use of protocol 'P' as a type must be written 'any P'
                       // ❌ Use of protocol 'Q' as a type must be written 'any Q'

4. In the Xcode menu bar, "Editor" > "Fix all issues (Cmd + Ctrl + Option + F)".

5. The error continues and the build fails.

Expected behavior
After "Fix all issues (Cmd + Ctrl + Option + F)", C & P should be replaced with any C & P, and P & Q should be replaced with any P & Q in one shot.
