[Request] Open VSCode as Workspace

### Feature summary

A new button to open VSCode instantly as a workspace

### What problem are you trying to solve?

Currently i need to use the open VSCode Button, wait for t he message "this folder contains a workspace file... Do you want to open it?", i click on "Open Workspace" and need to wait again for loading.

We could skip that if it would be possible to open the workspace directly from the copilot app.

### Proposed solution

A new Button to open the Workspace in VSCode directly

### Workflow impact

It would remove the additional step to open the workspace manually

### Installation context

_No response_

### Additional context

_No response_

Start by locating the existing Open VSCode button and the flow that handles a workspace file. Check how the Copilot app launches VSCode and where the workspace-open prompt is triggered. Done means a new button or equivalent action opens the workspace directly without requiring the extra confirmation step.
