Rule `PSAvoidShouldContinueWithoutForce` doesn't enforce correct use of the `Force` parameter

Currently PSScriptAnalyzer shows a PSAvoidShouldContinueWithoutForce violation for any scripts using $PSCmdlet.ShouldContinue that do not include a $Force parameter.
However, once the parameter the violation is resolved; even if that parameter is never used elsewhere in the code.

Steps to reproduce

function Invoke-MVP {
    [CmdletBinding(SupportsShouldProcess = $true)] 
    [OutputType('System.String')]
    Param (
        [Parameter()]
        [switch]$Force # Including this parameter resolves the PSAvoidShouldContinueWithoutForce violation; even though we don't reference Force in the rest of the code
    )
    if ($PSCmdlet.ShouldContinue('Should I continue','Should I continue')) {
        'I continued'
    }
}

# ...
Invoke-ScriptAnalyzer -Path '.\Invoke-MVP.ps1'

Expected behavior

A violation of rule PSAvoidShouldContinueWithoutForce should occur.

Actual behavior

The code is deemed free of violations.

Inizia individuando l’implementazione della regola PSAvoidShouldContinueWithoutForce e i test esistenti, quindi riproduci il problema con l’esempio Invoke-MVP del report. Il lavoro è completato quando un parametro Force inutilizzato non sopprime più la violazione e un test di regressione copre questo caso.
