Update Roslynator, improve type clarity, and reformat code

Updated `Directory.Build.props` to change `Roslynator.Analyzers` version from `4.12.7` to `4.12.8`.
Added a period to the comment in `ICommand.cs`.
Explicitly used `string` type instead of `var` in `MongoOutboxInitializer.cs`.
Reformatted `channel.ExchangeDeclare` calls and changed `foreach` loop variable to `string?` in `RabbitMqExchangeInitializer.cs` for better readability and type clarity.
