Example 2 of Install-ChocolateyPowerShellCommand has a duplicated parameter

### What You Are Seeing?

On [this page](https://docs.chocolatey.org/en-us/create/functions/install-chocolateypowershellcommand#examples), Example 2 contains `PSFileFullPath` twice. This will actually result in a parsing error from PowerShell:

```powershell
PS> Get-ChildItem -Recurse -Recurse
Get-ChildItem : Cannot bind parameter because parameter 'Recurse' is specified more than once. To provide multiple values to parameters that can accept multiple values, use the array syntax. For example, "-parameter
value1,value2,value3".
At line:1 char:24
+ Get-ChildItem -Recurse -Recurse
+ ~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Get-ChildItem], ParameterBindingException
+ FullyQualifiedErrorId : ParameterAlreadyBound,Microsoft.PowerShell.Commands.GetChildItemCommand
```

### What is Expected?

The example should work without parsin error.
