Changelog

实现 walkthroughs contribution API

[Ricbet]

• 基础 walkthroughs 贡献点渲染（标题、step、media）
• step description 渲染并支持 command、when
• media image 渲染
• media svg 渲染
• media svg command 事件处理
• media markdown 渲染（需支持资源以相对路径的方式打开）
• completionEvents 机制（例如当用户做了某些操作之后给当前 step 设置成 completion 的状态，也就是会在左边的 checkbox 打勾勾）
• 主题适配
