VSCode Bug with Devcontainers - High CPU Usage on ARM Macs

[dbarrous]

There has been a reported bug since the September 2022 release of VS Code where on some ARM Mac machines, there seems to be an extremely long time trying to verify extension signatures, causing high CPU usage.

Issue to Watch - microsoft/vscode#174632

A temporary solution until VS Code fixes it is to add this to your manually .devcontainer:

{
	"name": "foobar",
	"customizations": {
		"vscode": {
			"settings": {
				"extensions.verifySignature": false
			}
		}
	}
}

Not adding this to the .devcontainer since not verifying signatures as default is a bad idea.
