Update `ILogger` documentation to clarify formatter behavior when using extension methods

[enioluwas]

Summary

As described in the issue, the ILogger extension methods defined in LoggerExtensions pass in a formatter that ignores the exception parameter passed in. This is being made clear so that developers do not assume otherwise.

Fixes #10318
