 - `DEFAULT_ACTIONS_URL`: **github**：获取操作插件的默认平台，`github`表示`https://github.com`，`self`表示当前的 Gitea 实例。
 - `STORAGE_TYPE`: **local**：用于操作日志的存储类型，`local`表示本地磁盘，`minio`表示与S3兼容的对象存储服务，默认为`local`，或者使用定义为`[storage.xxx]`的其他名称。

 `DEFAULT_ACTIONS_URL` 指示 Gitea 操作运行程序应该在哪里找到带有相对路径的操作。
 例如，`uses: actions/checkout@v4` 表示 `https://github.com/actions/checkout@v4`，因为 `DEFAULT_ACTIONS_URL` 的值为 `github`。
