What is the issue?

Installing Pester using Install-PSResource triggers a warning about missing Modules folder in PATH environment variable. This affects all recent Pester versions

PS> Install-PSResource Pester 

WARNING: The installation path for the script does not currently appear in the CurrentUser path environment variable. To make the script discoverable, add the script installation path, /home/vscode/.local/share/powershell/Modules, to the environment PATH variable.

Expected Behavior

No warning

Steps To Reproduce

Install-PSResource Pester

Describe your environment

No response

Possible Solution?

Trying to fix in PSResourceGet first, see PowerShell/PSResourceGet#1043.

The warning is a side effect of the file Pester.ps1, marking Pester with isScript = true which is later used in the warning-check if (!_savePkg && isScript). Changing the latter to if (!_savePkg && isScript && !isModule) should suffice.

If not approved, we need to rename Pester.ps1 to something else.
