Transform HelloZeroNet from user into an organization

Currently it's a bit strange that HelloZeroNet is a user with all the repositories in that account.

To get more contributors on board and showcase the project better, it would be good to transform the user into an organization.

首先检查当前的 HelloZeroNet 用户账户及其仓库，然后确定将该账户转换为 GitHub 组织所需的步骤。项目由一个组织代表、仓库仍然可用，并且贡献者可以按预期完成入驻，即表示完成。
