Made AsyncApiSchemaOptions inherit from JsonSchemaGeneratorSettings

[Simkortet]

Recent change to NewtonsoftJsonSchemaGeneratorSettings does not allow compatibility with System.Text.Json and forces users of the saunter library to introduce newtonsoft into their projects.

First off, it doesn't compile.
Also looking at the commentary from the PR that introduced the change in the first place, it looks like it needs a bigger redesign than simply changing the basetype here.

That and there seems to be quite a few whitespace changes here as well.

Even if it compiled, you'd still have the newtonsoft dependency stemming from the SerializerSettings (without looking at the rest of the changes that introduced this dependency)
