Issue description

Is it possible to specify winpty.exe full path via Environment Variable? I installed it in MSYS2 but I don't what to expose all bins to my PATH.

Why are you asking? winpty should be is shipped with node-pty and it gets imported relatively here:

https://github.com/microsoft/node-pty/blob/efbf8ebbe7b09351548fa0a4ed07b36c5d2e539b/src/windowsPtyAgent.ts#L77-L89

I installed is with pnpm and it cannot find winpty automatically.

Node.js v20.15.0

After I download winpty by myself and added it to PATH, is can run.

And I cannot find winpty.exe anywhere.

winpty is definitely compiled after yarn is run (or npm i after https://github.com/microsoft/node-pty/pull/721). Maybe this is an issue with pnpm?
