Private parameters are reported as unused

Comece executando Invoke-ScriptAnalyzer na reprodução em PowerShell e inspecione a implementação e a cobertura da regra PSReviewUnusedParameter. Confirme que o parâmetro privado e seu uso final são reconhecidos como a mesma variável; considera-se concluído quando a reprodução não produz nenhum aviso de parâmetro não utilizado.

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

Run the analyzer against this script.

Param (
    [String] $private:var1
)

function Test-Second
{
    # $var1 is not accessible because it was private to the script.
    Write-Information -InformationAction "continue" "From script: $var1"

    # $var2 is not private to the calling function so we can access it.
    Write-Information -InformationAction "continue" "From caller: $var2"
}

function Test-NotGlobal
{
    Param (
        [String] $var2
    )
    $a = $var1 + " " + $var2
    Write-Information -InformationAction "continue" "Concatenation: $a"
    Test-Second
}

Test-NotGlobal $var1

Expected behavior

Expect no errors because $private:var1 and the use in the last line of $var1 are the same variable and $var1 is private to the script, as required.

Actual behavior
