[vscode] Require force-restart onUpdate of extension

[vanshb03]

Proposed Solution:

• Add a check in the extension to detect when an update has been applied.
• Display a notification to the user informing them that a restart is required.
• Provide a button or command in the notification to restart VS Code. (workbench.action.reloadWindow)

Expected Behavior:

After updating the extension, users should see a notification prompting them to restart VS Code. Clicking the notification should restart VS Code automatically, ensuring that the update is applied without manual intervention.
