[log][v2] There is no information on how to change the log levels for each target

I've setup the log exactly how it's specified in the documentation, but the file and stdout are getting flooded with TRACE logs. How can I change the level of the logs that go there?

Review the Tauri plugin v2 logging documentation and the configuration for individual log targets. Clarify how users set different log levels for file and stdout targets, and consider the reported TRACE flooding as the example. Done when the documentation gives an unambiguous configuration path for changing each target's level.
