fetch-configlet.ps1: "Cannot validate argument" error

[ee7]

From a forum thread:

bin$ pwsh ./fetch-configlet.ps1
Invoke-WebRequest: /mnt/c/Users/bugma/Source/Repos/3rdParty/euphoria/bin/fetch-configlet.ps1:29
Line |
  29 |  Invoke-WebRequest -Uri $downloadUrl -OutFile $outputFile @requestOpts
     |                         ~~~~~~~~~~~~
     | Cannot validate argument on parameter 'Uri'. The argument is null or
     | empty. Provide an argument that is not null or empty, and then try
     | the command again.

This looks different from the error in #786.

See #841

@ErikSchierboom do you want to sync the fetch-configlet scripts Exercism-wide?

[ErikSchierboom]

Yes, I'll do that.
