Feature Request: Support disabling `--wait` during notarization

Currently `electron/notarize` waits for Apple's notarization process to complete. In CI environments like GitHub Actions, this can block the runner for several minutes because Apple's notarization service can be slow.

It would be helpful if the library supported an option to disable the `--wait` behavior so that developers can submit the notarization request and check the result later.

For example:

```js
await notarize({
appPath,
appleId,
appleIdPassword,
teamId,
wait: false
})
```

This would allow CI workflows to submit notarization and then poll the status separately using `notarytool info`, reducing unnecessary runner time.

If this feature makes sense, I'd be happy to open a PR to implement it.
