Mention LoggerMessageAttribute on the page of rule CA1848

> Instead of using the [LoggerMessage class](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.logging.loggermessage) to create high-performance logs, you can use the [LoggerMessage attribute](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.logging.loggermessageattribute) in .NET 6.0. The LoggerMessageAttribute provides source-generation logging support designed to deliver a highly usable and highly performant logging solution for modern .NET applications. For more information, see [Compile-time logging source generation (.NET Fundamentals)](https://learn.microsoft.com/en-us/dotnet/core/extensions/logger-message-generator).
