Fix the issue with the status bar icon

In the 2023.3 EAP call to isAvailable seems to happen much earlier than it used to be.
This caused the fact that `injector` is not yet initialised at that moment and we fail with an exception. All other status bar icons are also not loaded because of this exception.
Adding `VimPlugin.getInstance()` is a quick workaround to initialize the needed injector
