Don't working properly with generic instantiation of slice

[0x9ef]

Describe the bug
Don't working properly with parametric generics
panic: interface conversion: ast.Expr is *ast.ArrayType, not *ast.StructType

To Reproduce
Steps to reproduce the behavior:

1. Create main.go with the next content (listed below)
2. Run "swag init"
3. See error

Content:
pgjson.go

package pgjson

import (
	"database/sql/driver"
	"encoding/json"
	"errors"
	"fmt"
)

func Scan(dest interface{}, value interface{}) error {
	switch t := value.(type) {
	case string:
		return json.Unmarshal([]byte(t), dest)
	case []byte:
		return json.Unmarshal(t, dest)
	default:
		return errors.New(fmt.Sprint("failed to unmarshal JSON value:", value))
	}
}

func Value(src interface{}) (driver.Value, error) {
	value, err := json.Marshal(src)
	return string(json.RawMessage(value)), err
}

type Slice[T any] []T

func (j *Slice[any]) Scan(value interface{}) error {
	return Scan(j, value)
}

func (j Slice[any]) Value() (driver.Value, error) {
	if len(j) == 0 {
		return "[]", nil
	}
	return Value(j)
}

main.go

package main

import "main/pgjson"

type controller struct{}

type Destination struct {
	Images pgjson.Slice[string] `json:"images,omitempty"`
} // @name Destination

type doSomethingBody struct {
}

type doSomethingResponse struct {
	*Destination
}

// @ID           DoSomething.
// @Summary      Do something.
// @Accept       application/json
// @Produce      application/json
// @Param        fields body doSomethingBody true "data"
// @Success      200 {object} doSomethingResponse
// @Failure      422,500 {object} Error
// @Router       /doSomething [POST]
func (c *controller) doSomething() {}

func main() {
	c := &controller{}
	c.doSomething()
}

Expected behavior
Should generate docs correctly without any errors

It can be fixed by adding swaggertype:"array,string" as a tag to structure field. But is there a way to implement it automatically by parsing generic instantiation type parameter?
