[Error UX Improvements]: "Downloading VS Code server failed. Please try again later."

[tbombach]

Let's improve the error message experience when users encounter this error. The ideal experience is actionable and specific to minimize friction for users. For example, a user could press a button in the error dialog to fix the issue. Or they could have a link that takes them directly to documentation for a complex issue. If they need to navigate to the Studio, we could provide a link to direct them to the right UI/tab as much as possible.

Context: The installation script was not able to connect to the VS Code CDN to download the server bits. The user likely has firewall settings blocking the host
