Let's Move 一项学 Move 获得 SUI 的激励计划，鼓励更多的人学习 Move 语言
学习日志 (alva-lin)
任务
完成 NFT 相关知识的学习
完成可以 mint NFT 的合约上链
给自己地址 mint 一个 NFT
mint 一个 nft 发送到地址:
0x7b8e0864967427679b4e129f79dc332a885c6087ec9e187b53451a9006ee15f2
主要参照 创建 NFT - Sui Move by Example (中文版)
NFT 合约代码如下，包含了 NFT 的定义，各类事件以及 entry function。
首先切换到主链，并发布
拿到发布的 package ID，然后调用公共方法
再将 mint 的 NFT，转移给指定地址
