chore: specify yarn package manager version

[A-kirami]

概述

更新了 package.json 文件，明确指定了 Yarn 包管理器的版本，以确保项目中的依赖管理保持一致。

为什么

Yarn 官方不推荐全局安装，在它们的官方文档中可以看到以下理由：

You may notice by reading our installation guide that we don't tell you to run npm install -g yarn to install Yarn - we even recommend against it. The reason is simple: just like your project dependencies must be locked, so should be the package manager itself.

Installing Yarn as a global binary meant you always used whatever was the latest version published. Most of the time it worked fine, but every once in a while something was shipped that could impact the way your project was installed - be it a bugfix, new bug, or breaking change.

通过指定 packageManager，可以使用 Corepack 按项目安装所需的包管理器版本。

此举还可以避免本地开发时多个 Yarn 版本冲突问题。
