@spec resolve_schema_modules(OpenApiSpex.OpenApi.t()) :: OpenApiSpex.OpenApi.t()

Adds schemas to the api spec from the modules specified in the Operations.

Eg, if the response schema for an operation is defined with:

responses: %{
  200 => Operation.response("User", "application/json", UserResponse)
}

Then the UserResponse.schema() function will be called to load the schema, and a Reference to the loaded schema will be used in the operation response.

See OpenApiSpex.schema macro for a convenient syntax for defining schema modules.
