I've recently entered the realm of tech and decided to give VS Code a try. After downloading it, I installed several extensions, but unfortunately some of them aren't functioning properly. My primary issue is with the HTML5 boilerplate extension. Instead of working as expected, it's displaying an error message on the runtime status bar that reads: "unknown language in 'contributes.HTML5-boilerplate.language'. provided value: njk". I'm feeling lost and unsure of how to resolve this problem. Any assistance would be greatly appreciated.
