Swift package add-dependency command doesn't update all Package.swift files

[cmcgee1024]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

There can be multiple Package.swift files targeting different toolchain version ranges. For example, a file named Package@swift-5.8.swift will be used with a 5.8 or newer toolchain.

When running swift package add-dependency <url> --from <x.y.z> SwiftPM only updates the Package.swift file, and not any of the other ones. Try this with the swift-argument-parser package as an example.

Expected behavior

This command should update all available Package.swift files, or produce errors/warnings on the ones that it could not update.

Actual behavior

No response

Steps to reproduce

Do you think this could also be useful for other subcommands too such as add-target, add-target-dependency. add-product, and add-setting?
