Fix slop remains (#4640)

* Fix slop remains

Chris likes to vibe code. AI likes to use different types of dashes (em-dashes, en-dashes), instead of regular dashes (-).

On PowerShell 7 this appears to work. The parser doesn't care. But, what about PowerShell 5? It begins throwing errors about the ampersand. Loading it in the ISE reveals how it stops parsing the syntax correctly when it encounters em-dashes. Rather than displaying them as such, the ISE displays them as —.

Chris, if you want to vibe code, I don't mind. But at least use regular dashes.

Anyway, I won't fix the AI code. I just want to make it work on my beloved powershell 5.
