Gitea 1.22.3 Docker部署（TrueNAS）推送失败：pre-receive钩子解码错误

在TrueNAS上通过Docker运行Gitea 1.22.3时，推送代码至Git仓库触发错误。经确认，移除仓库目录下的pre-receive钩子文件git/repositories/user/somerepo/hooks/pre-receive.d/gitea后，推送可正常执行。

错误日志 #

排查情况 #

• 使用搭载TrueNAS证书的HTTPS协议推送，问题复现；切换为HTTP协议后，问题仍存在。
• 执行gitea doctor check命令，所有检查项均显示正常，输出如下：
