feat: 添加 markdown 语法及格式检查，添加 autoreview 工作流

[TonyCrane]

• 使用 autocorrect 进行中英文混排的格式检查，一定程度上补充了 tools/punctuation_checker.py 的功能（仍有一部分规则 autocorrect 无法检测，无法完全替代）
• 使用 markdownlint 进行 markdown 语法检查
• 本 PR 中已使用这两工具对现有文档进行了格式修复
• 添加了 autoreview workflow，利用 ReviewDog 来将检测结果自动上传到 code review 结果
• 将原有的 punctuation checker 去掉被 autocorrect 覆盖的部分，并接入 ReviewDog

目前剩余：

• 转为使用 ReviewDog
• 将原有 checker 中被覆盖的部分规则删去，并接入 ReviewDog
• 添加本地检测指南
• 检查现有自动修改是否会导致渲染问题
