Need more information on when and how to use this interface

### Type of issue

Missing information

### Description

This interface appears to be useful for capturing additional information into a structured form usable by structured loggers. But there is no documentation on the actual usage of this interface nor any examples. The only reason I found this is because of the extension method, that is also not well documented, over [here](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.dependencyinjection.httpclientloggingservicecollectionextensions.addhttpclientlogenricher?view=net-9.0-pp).

It would be nice to get some discussion on when this is useful and what to do with it. While I can see where it is possible to add a new enricher, the `IEnrichmentTagCollector` that enrichers write to doesn't seem to be accessible anywhere else. So if I wanted to use an enricher to add some data to logging then I could create my own enricher. But I don't see any way to later write a logger, or whatever, that then has access to this collection of enriched data.
