[Enhancement] 添加自动修复工作流 (#337)

* feat: add GitHub Action to automatically strip EXIF data and compress images via PR comments

* fix: 提升尝试压缩后修复失败的用户体验

* feat: 现在修复结果会直接基于源 comment 做 update

* fix: 修复工作流仍然报告失败的问题

* doc: 添加自动修复引导

* ci: 改用 `github.rest.repos.compareCommitsWithBasehead`

* ci: 增强检查工作流
