openapi schema 3.0 yaml warnings and inline_response_ files are not generating in go server stub code

1. i created my yaml with openapi 3.0 specification

2. generated the go server stub code and getting below warnings.

3. WARN - o.o.codegen.utils.ModelUtils - Multiple schemas found, returning only the first one

4. WARN o.o.codegen.DefaultCodegen - The following schema has undefined (null) baseType. It could be due to form parameter defined in OpenAPI v2 spec with incorrect consumes. A correct 'consumes' for form parameters should be 'application/x-www-form-urlencoded' or 'multipart/form-data'

One more Observation like model_inline_response_*.go files are not generating which are generated in 2.0.

Start by reproducing Go server stub generation with the reported OpenAPI 3.0 YAML and compare it with the 2.0 output. Investigate the listed warnings and the missing model_inline_response_*.go files; done means the relevant warnings are resolved and the expected inline response files are generated.
