corepack seems to obey LOCALAPPDATA silently

首先使用通过 WSLENV 传递 LOCALAPPDATA 和 APPDATA 的 WSL2 配置重现问题，然后跟踪在执行 corepack enable 和 yarn install 期间 dist/lib/corepack.cjs 中失败的重命名操作。当 Corepack 能够在此环境中正常工作且不出现 EACCES 错误，并且该行为由适当的回归测试覆盖时，即视为完成。

Platform : WSL2

If because of reasons you have WSLENV=WT_SESSION:WT_PROFILE_ID:LOCALAPPDATA/p:USERPROFILE/p:APPDATA/p to pass through LOCALAPPDATA & APPDATA to your WSL2 environment then you get permissions errors when trying to use yarn + corepack

bsh ❯ corepack enable

This never used to happen, and I'm not sure if it's 'yarn' or 'corepack' that is the issue (there aren't any PRs or issues that mention appdata that seem related).

My current workaround is to use direnv to unset both those environment variables
