Bug：generate types code

[tanberBro]

Bug description

Generated types code, containing useless models.

Reproduction

          example: application
        scope:
          type: string
          example: namespace
        name:
          type: string
          example: 应用
        children:
          type: array
          items:
            $ref: '#/components/schemas/ResourceTree'
        createTime:
          type: string
          example: 2006-01-02 15:04:05.000
        updateTime:
          type: string
          example: 2006-01-02 15:04:05.000
      required:
        - code
        - scope
        - name
        - children
        - createTime
        - updateTime

execute command

oapi-codegen -package health -generate types -include-tags health openapi.yaml > types.gen.go

types.gen.go

// Package health provides primitives to interact with the openapi HTTP API.
//
// Code generated by github.com/deepmap/oapi-codegen/v2 version v2.0.0 DO NOT EDIT.
package health

// ResourceTree defines model for ResourceTree.
type ResourceTree struct {
	Children   []ResourceTree `json:"children"`
	Code       string         `json:"code"`
	CreateTime string         `json:"createTime"`
	Name       string         `json:"name"`
	Scope      string         `json:"scope"`
	UpdateTime string         `json:"updateTime"`
}

Expected behavior

The above should not contain the ResourceTree structure in the generated types.gen.go file, it should only appear in the interface types file that references it.

Hi, are you expecting that the usage of include-tags would make sure that only types that are referenced by paths with the tag health get included? (If so, I think that makes sense, and would be something for us to improve on)
