Unable to pass extra build arguments to the builder

[bravecobra]

I need to pass extra arguments to the builder like /PublishSingleFile false or /PublishReadyToRun false in order to support .NET 5.0
The current syntax does not allow that.
I'm able to hack it in through the relative path property as that is just appending.

settings.RelativePath = $". /PublishSingleFile false /PublishReadyToRun false";

but this should get its own property imho.
