Theme suggestion dialog should not offer workspace option when no workspace is open

[gjsjohnmurray]

Start a new VS Code window that doesn't use an InterSystems theme. Open a file (not a folder or a workspace). Set the file's language mode to ObjectScript. Dialog proposing the InterSystems theme includes "Only This Workspace" option. That's not applicable in this situation.

Code pointer:

language-server/client/src/extension.ts

Lines 91 to 105 in ddbbecc

	// Suggest an InterSystems default theme depending on the current active theme type
	if (window.activeColorTheme.kind === ColorThemeKind.Light) {
	const answer = await window.showInformationMessage(
	`For the best user experience, InterSystems recommends that you activate the default light theme included with the [InterSystems Language Server extension](https://marketplace.visualstudio.com/items?itemName=intersystems.language-server). Activate now?`,
	"Globally",
	"Only This Workspace",
	"Don't Ask Again"
	);
	if (answer === "Globally") {
	workspace.getConfiguration("workbench").update("colorTheme","InterSystems Default Light",true);
	}
	else if (answer === "Only This Workspace") {
	workspace.getConfiguration("workbench").update("colorTheme","InterSystems Default Light",false);
	}
	else if (answer === "Don't Ask Again") {

@gjsjohnmurray What's the best way to test if a workspace is open? workspace.name !== undefined?

[gjsjohnmurray]

Indeed, the spec at https://code.visualstudio.com/api/references/vscode-api#workspace says of workspace.name

The name of the workspace. undefined when no folder has been opened.
