When creating a new client / plugin from Kiota without an opened workspace, we should deeplink in the extension

### Is your feature request related to a problem? Please describe the problem.

When creating a new client or plugin from the extensions when no folder (workspace) is selected, we open a new VS Code extension window but we don't focus the kiota extension with the loaded client.

### Client library/SDK language

None

### Describe the solution you'd like

When opening, I would love to see the API loaded in the API Explorer so I can continue working on it.

### Additional context

_No response_

Start by tracing the Kiota VS Code extension flow used when creating a client or plugin without an opened workspace. Check how the new extension window is opened and how the API Explorer loads an API; done means the new window focuses Kiota with the created API loaded in the explorer.
