Handle reconnect for GLSP VS Code integration

Follow-up of #77

Ensure reconnect handling is properly implemented for the GLSP VS Code integration

[planger]

@ndoschek Is this ticket only about the example or for VS Code in general. To me this has an impact on the priority. If it is "just" the example I'd say prio is low. If this change is needed for VS Code reconnect support in general, it is rather P1. Thanks!

Hi @planger, you're right, thanks for double checking! Yes, it is rather targeting the VS Code integration support and not only the example. I adapted the title and description.
So I'd agree to say the P1 priority is correct here.
