    .EXAMPLE
        Remove-SensitiveData -InputObject [PSCustomObject] @{ IncomingWebhookUri = $incomingWebhookUri }
        Returns the input object with the value of the IncomingWebhookUri key set to
        '[REDACTED]', unless the $Script:PSRyver.ForceVerbose PSRyver module
        configuration parameter is set to $true, in which case the value would not be
        masked.
 
    .EXAMPLE
        [PSCustomObject] @{ PlainText = 'do not display' } | Remove-SensitiveData -SensitiveProperties 'PlainText'
        Returns the object input via the pipeline with the value of the 'PlainText' key
        set to '[REDACTED]', because the SensitiveProperties parameter specified this
        key as sensitive.
 
    .EXAMPLE
        Remove-SensitiveData -InputObject [PSCustomObject] @{ Authorization = $authorization } -ForceVerbose
        Returns the input object with the value of the Authorization key intact
        regardless of whether or not the $Script:PSRyver.ForceVerbose PSRyver module
        configuration parameter is set to $true, because the ForceVerbose parameter
        mandated this.
 
    .EXAMPLE
        Remove-SensitiveData [PSCustomObject] @{ Authorization = $authorization }
        Uses a positional parameter Returns the hashtable with the Uri value set to '[REDACTED]'.
