Missing 4.1 feature documentation - Windows Exporter Metrics input plugin (extended)

[eschabell]

Missing new details from 4.1 release:

Observability & Metrics - Extended Windows Exporter Collectors (TCP paging, Cache, Logical Disk…)

Update to existing documentation location: https://docs.fluentbit.io/manual/data-pipeline/inputs/windows-exporter-metrics

[eschabell]

I can test and update this once back in NL (currently traveling).
