Modal warning about 'detect node runtime' is too eager

[gjsjohnmurray]

Let's make it wait more than 5 seconds:

vscode-sqltools/packages/extension/src/language-client/detect-node-path.ts

Lines 10 to 14 in 3e7bbb1

	const failureMessageTimer = setTimeout(() => {
	window.showWarningMessage("Check Terminal view for an erroring 'detect node runtime' session. Capture details for investigation, then kill the terminal to continue SQLTools extension startup. Change the 'sqltools.detectNodeRuntime' setting to disable runtime detection.",
	{ modal: true });
	commands.executeCommand("terminal.focus");
	}, 5000);
