Serial monitor throws error when trying to retrieve the `enumerateMonitorPortSettings` and the platform is not installed

[kittaakos]

Describe the problem

When I have a fresh installation and select my Zero board, the serial monitor throws an error. It's in the logs:

Language server, user fields, boards config, etc., correctly handle when the platform is not installed. It's unhandled by the monitor.

To reproduce

• Rename the directories.data location,
• Start IDE2 from a terminal,
• Attach your Zero board while the Monitor widget is opened,
• IDE2 tries to start the monitor, but it fails,
• See error.

Expected behavior

The monitor logic gracefully handles when the platform of the currently selected board is not installed.
