added v1.5.25 release notes

[Aaronontheweb]

1.5.25 June 17 2024

• Update Akka.Hosting to 1.5.25
• implicitly convert regular BusLogger to SerilogLoggingAdapter when ForContext is called

As of Akka.Logger.Serilog v1.5.25, you can now do the following:

var log = Context.GetLogger()
    .ForContext("Address", "No. 4 Privet Drive")
    .ForContext("Town", "Little Whinging")
    .ForContext("County", "Surrey")
    .ForContext("Country", "England");
log.Info("My boss makes me use {Semantic} logging", "semantic");

And it will work without having to explicitly call Context.GetLogger<SerilogLoggingAdapter>() first.

close #290
