博客友链页面修改

去除link-intro，修改link-title的 style 使得上下居中

<div class="card-content">
	<div class="link-avatar my-auto">
		<img th:src="${link.spec.logo}"
		th:alt="${link.spec.displayName}" />
	</div>
	<div class="link-text">
		<div class="link-title"  th:text="${link.spec.displayName}" 
		style="display: flex; flex-direction: column; justify-content: center; height: 100%;">
		</div>
		<!-- <div class="link-intro" th:text="${link.spec.description}">
		</div> -->
	</div>
</div>
