* chore(go): add failing test for JSON marshalling
Adds a small schema (FruitJuice) which contains a required gmFruit,
which inherits using AnyOf. This fails to correctly marshal as JSON.
* fix(go): use non-pointer receiver for JSON marshal
In the case of a required anyOf property, JSON marshalling would has
been incorrect.
Required properties are not nullable, and thus always use value
receivers. For the single case of anyOf models, a pointer receiver was
used for MarshalJSON. All other instances of json marshalling use value
receivers.
This change is simply to use a value receiver instead of a pointer
receiver in the template for `MarshalJSON` on anyOf models.

* [Go] Fix deepObject serialization that are anyOf
Updates the go client generator to have the generated struct for anyOf types conform to `MappedNullable` interface.
Fixes query params serialization for deepObjects that are of `anyOf` type.
Implements the suggestion in https://github.com/OpenAPITools/openapi-generator/issues/19085
* check parameter style for deepObject serialization
* generate samples for go-echo-external-refs-test
* move test back to http port
* restrict to anyof models with discriminator
* update test
* add some tests
added some tests to `modules/openapi-generator/src/test/resources/3_0/go/petstore-with-fake-endpoints-models-for-testing-with-http-signature.yaml` and regenerated the samples
