Hot restart keybinding not working anymore

Thanks for the feedback! If your issue is related to the Flutter framework itself,
please open an issue at
[github.com/flutter/flutter](https://github.com/flutter/flutter/issues/new).

## Steps to Reproduce

* Install intellij 2023.1 and latest flutter plugin.
* Open a flutter project
* Press `ctrl + shift + \`

The ide will open a popup instead of doing hot restart.
