x/website: command to update PATH only works on cmd.exe on windows

Error on page https://golang.org/doc/tutorial/compile-install

In step 3, the Windows command needs double quotes around the path to work.

You're using PowerShell; the instructions are for Command shell. Should it give separate instructions for PowerShell? The PS way to revise path is:

$env:Path += ";C:\Program Files\xyz\bin"

[oddlittlebird]

Either give separate instructions or make very clear to Windows users which terminal they should use.
