Update metrics used in GA4 All Traffic Widget for consistency

[aaemnnosttv]

Bug Description

In #6639 we changed the source links in GA4 dashboard widgets to point to the correct locations in the GA4 reporting interfaces on the service. In doing so, a few of the metrics that are used within the All Traffic Widget were changed to use the incorrect users metric activeUsers instead of totalUsers. This is likely due to an oversight when trying to match the destination URL since GA4 uses activeUsers by default on the service.
