Temp Fix for Slow pnpm install/update/remove

[YFengFly]

After using pnpm for a while, it's become unbearably slow.
#7133
In this issue @zkochan mentioned, "pnpm is too slow is too broad","But with this title and description the issue just attracts people with different unrelated issues".After seeing this, I decided to delete all the node_modules directories installed via pnpm, as well as the .pnpm-store, and then ran Get-ChildItem -Recurse | Where-Object {$_.LinkType -eq 'HardLink'} in Windows PowerShell to ensure all pnpm hard links were cleaned up.

I saw a discussion that offered a great method, and I would recommend doing it like this:

Deleting all node_modules folder and running pnpm store prune

The execution speed improved significantly afterwards. For example, with the store, pnpm install used to take over 30 minutes, but now, without the store, the first pnpm install only takes 6 minutes.
In this case, the slow speed was due to the impact of hard links. After a clean removal, the speed returned to normal.
Hopefully, this method will be helpful.
