fix: unexpected behavior while pulling resources (#3789)

fix: unexpected behavior while pulling resources

在 commit 25cfd162f6 中引入新的 pnpm prepare 执行脚本指令，而 prepare 关键字与包管理器的生命周期脚本冲突。导致在运行 Workflow 的时候被执行两次资源拉取，并且被当做生命周期脚本的时候没有携带预期的 \`${{ matrix.target }}\`。这一行为进一步影响 macOS Intel X86 平台上的构建。

所影响的 issues: #3753, #3771
