Esoteric Error when a class-based DSC Resource has a property named `Scope`

### Prerequisites

- [X] Write a descriptive title.
- [X] Make sure you are able to repro it on the [latest released version](https://www.powershellgallery.com/packages/PSDesiredStateConfiguration)
- [X] Search the existing issues.

### Steps to reproduce

When I define a DSC Resource as a PowerShell class, I should be able to use arbitrary names for the properties, so long as they're not one of PowerShell's [automatic variables][01].

1. Create a new folder, `dsc-repro`:

   ```powershell
   New-Item ./dsc-repro -ItemType Directory
   Push-Location ./dsc-repro
   ```

1. Define a new PowerShell module manifest, `dsc-repro.psd1`, with the following manifest:

   ```powershell
   New-ModuleManifest -RootModule dsc-repro.psm1 -DscResourcesToExport ReproInvalid, ReproValid
   ```

1. Define the root module with the following code:

   ```powershell
   [DscResource()] class ReproInvalid {
       [DscProperty(key)] [string] $Scope
       [ReproInvalid] Get() {
           $actual =  [ReproInvalid]::new()
           $actual.Scope = $this.Scope
           return $actual
       }
       [bool] Test() { return $true }
       [void] Set() { }
   }

   [DscResource()] class ReproValid {
       [DscProperty(key)] [string] $ConfigurationScope
       [ReproValid] Get() {
           $actual =  [ReproValid]::new()
           $actual.Scope = $this.ConfigurationScopeScope
           return $actual
       }
       [bool] Test() { return $true }
       [void] Set()  { }
   }
   ```

1. Call `Get-DscResource` for the module's DSC Resources:

   ```powershell
   # Add the local folder to the PSModulePath
   $env:PSModulePath += [System.IO.Path]::PathSeparator + $pwd.Path
   Get-DscResource -Module dsc-repro
   ```

   ```Output
   MethodInvocationException:
     Exception calling "ImportClassResourcesFromModule" with "3" argument(s):
       "Syntax error:   At line:4, char:21  Buffer:  {     [key]string Scope^; }; "
   ```

1. Comment out the definition for `ReproInvalid`:

   ```powershell
   # [DscResource()] class ReproInvalid {
   #     [DscProperty(key)] [string] $Scope
   #     [ReproInvalid] Get() {
   #         $actual =  [ReproInvalid]::new()
   #         $actual.Scope = $this.Scope
   #         return $actual
   #     }
   #     [bool] Test() { return $true }
   #     [void] Set() { }
   # }

   [DscResource()] class ReproValid {
       [DscProperty(key)] [string] $ConfigurationScope
       [ReproValid] Get() {
           $actual =  [ReproValid]::new()
           $actual.Scope = $this.ConfigurationScopeScope
           return $actual
       }
       [bool] Test() { return $true }
       [void] Set()  { }
   }
   ```

1. Call `Get-DscResource` for the module's DSC Resources:

   ```powershell
   Get-DscResource -Module dsc-repro
   ```

   ```Output
   ImplementationDetail : ClassBased
   ResourceType         : ReproValid
   Name                 : ReproValid
   FriendlyName         :
   Module               : dsc-repro
   ModuleName           : dsc-repro
   Version              : 0.0.1
   Path                 : C:\code\dsc-repro\dsc-repro.psd1
   ParentPath           : C:\code\dsc-repro
   ImplementedAs        : PowerShell
   CompanyName          : Unknown
   Properties           : {ConfigurationScope, DependsOn, PsDscRunAsCredential}
   ```
