plugin/metrics: drop the nonexistent type label from request_duration_seconds (#8650)

Browse Source 
The RequestDuration histogram is declared with labels server, zone and view
only (plugin/metrics/vars/vars.go) and report.go observes it with those three
values. The type label belongs to requests_total, not to the duration
histogram, so remove it from the README metric list.
