feat: add Git user identity configuration for CI environments

- Implemented a check for Git user identity in the `pushManifestToRemoteRepo` function to handle cases where the identity is not configured in CI environments.
- Added logic to set a default CI user identity if none is found, ensuring smooth operation during automated deployments.

+这里需要增加判断 CI 中跑可能没有这个信息
+
+Author identity unknown
+
+*** Please tell me who you are.
+
+Run
+
+  git config --global user.email "you@example.com"
+  git config --global user.name "Your Name"
+
+to set your account's default identity.
+Omit --global to set the identity only in this repository.

+
+我看到你遇到了在 CI 环境中 Git 缺少用户身份配置的问题。我需要在 `pushManifestToRemoteRepo` 函数中添加 Git 用户身份的检查和配置。
+

+
+```diff
+  
+      logger.main.info('📤 开始推送更新到远程仓库...')
++ 
++     // 配置 Git 用户身份（特别是在 CI 环境中）
++     try {
++       // 检查是否已配置用户身份
++       await $({
++         cwd: assetsGitDir,
++         stdio: 'pipe',
++       })`git config user.name`
++     } catch {
++       // 如果没有配置，则设置默认的 CI 用户身份
++       logger.main.info('🔧 配置 Git 用户身份（CI 环境）...')
++       await $({
++         cwd: assetsGitDir,
++         stdio: 'pipe',
++       })`git config user.email "ci@photo-gallery.local"`
++       await $({
++         cwd: assetsGitDir,
++         stdio: 'pipe',
++       })`git config user.name "Photo Gallery CI"`
++     }
+  
+      // 检查是否有变更
+```
