Issue setting up powershell

[pr0xr]

I have issues setting up powershell on windows. The first issue seems to be in the string below. Removing the single quotes fixes this.

hygeia/src/commands/setup/powershell.rs

Line 37 in 712c5f2

let powershell_args = &["-Command", "'echo $profile'"];

The second is in the path itself, the backslashes needs to be escaped and there's also two hidden characters at the end of path. I used pop twice here and that fixes the string.
