Fix nodeName to UPPERCASE in insertStylesheetIntoRoot

[sweetliquid]

Summary

The condition node.nodeName === 'link' is always false, because node.nodeName is Uppercase in specification. And the condition node.nodeName === 'LINK' is unnecessary, because Fizz hoists tags when it's media attribute is "not all", whether it is a link or a style (line 36):

Lines 30 to 44 in 18cbcbf

	// Seed the precedence list with existing resources and collect hoistable style tags
	const nodes = thisDocument.querySelectorAll(
	'link[data-precedence],style[data-precedence]',
	);
	const styleTagsToHoist = [];
	for (let i = 0; (node = nodes[i++]); ) {
	if (node.getAttribute('media') === 'not all') {
	styleTagsToHoist.push(node);
	} else {
	if (node.tagName === 'LINK') {
	resourceMap.set(node.getAttribute('href'), node);
	}
	precedences.set(node.dataset['precedence'], (lastResource = node));
	}
	}

If there are any problems, please guide me. Thanks!

@gnoff seems legit, and if not could we add a test that would fail this?

[gnoff]

@sweetliquid the nodeName check is a shortcut to avoid the attribute lookup on link tags since it will likely be slower than just reading the node name. You're right thought that this is currently non-functional. But let's just fix it to uppercase so we can avoid the attr read for the majority of tags we process this way

[sweetliquid]

@gnoff I've added back the nodeName check and fix it to uppercase, thanks for your explanation~
