[shell] feat: close event on child process

[Ludea]

it could be awesome if this plugin get an event on closed child.

The command does emit a close event: https://v2.tauri.app/reference/javascript/shell/#example-1

Is that what you're asking for?

[Ludea]

Not at all, close event for spawned child process, not command
