PSResourceGet exports the $PSGetPath variable but never sets the value

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

In a new session import PSResourceGet but don't import PowerShellGet v2. Examine the value of $PSGetPath.

Expected behavior

PS> Get-Variable PSGetPath -ValueOnly

AllUsersModules    : C:\Program Files\PowerShell\Modules
AllUsersScripts    : C:\Program Files\PowerShell\Scripts
CurrentUserModules : C:\Users\sewhee\Documents\PowerShell\Modules
CurrentUserScripts : C:\Users\sewhee\Documents\PowerShell\Scripts

Actual behavior

PS> Get-Variable PSGetPath -ValueOnly
Get-Variable: Cannot find a variable with the name 'PSGetPath'.

Error details

No error.

The variable $PSGetPath was added to PowerShellGet v2 in https://github.com/PowerShell/PowerShellGetv2/pull/486. The variable is never used by the modules, it is provided to give users information about the location of the Modules and Scripts folder for each scope.

PSResourceGet exports the variable in the module manifest, but nowhere in code does it set the value.

Environment data

PS> gmo -list Microsoft.PowerShell.PSResourceGet

    Directory: C:\Users\sewhee\Documents\PowerShell\Modules

No response

Start by importing Microsoft.PowerShell.PSResourceGet without PowerShellGet v2 and reproducing the missing variable with Get-Variable PSGetPath. Inspect the module manifest export and the module initialization code, which the issue says never sets the value. Done means the variable is available after import and reports the four module and script paths shown in the expected behavior.
