Get-AZMetric Documentation: Example 4

### Type of issue

Code doesn't work

### Feedback

on example 4 of get-azmetric documentation it uses a object to store multiple new-azmetricfilter's - doing this causes an error:

example code:

$dimFilter = @((New-AzMetricFilter -Dimension City -Operator eq -Value "Seattle","Toronto"), (New-AzMetricFilter -Dimension AuthenticationType -Operator eq -Value User))
Get-AzMetric -ResourceId -MetricName PageViews -TimeGrain 00:05:00 -MetricFilter $dimFilter -StartTime 2018-02-01T12:00:00Z -EndTime 2018-02-01T12:10:00Z -AggregationType Average

this will result in the following error when done

Get-AzMetric : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'MetricFilter'. Specified method is not supported.

code used to throw the error (each segment works until i attempt to multiply the filters)

$filter = @((New-AzMetricFilter -dimension StatusCode -Operator eq -Value $d), (New-AzMetricFilter -Dimension CollectionName -Operator eq -Value $containerName))

$metric = Get-AzMetric -ResourceId $ids -MetricName "TotalRequests" -MetricFilter $filter -WarningAction Ignore -StartTime $start_time -EndTime $end_time
