You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: v257.go
    path of file: ./repos/gitea/models/migrations/v1_20
    
    the code of the file until where you have to start completion: // Copyright 2023 The Gitea Authors. All rights reserve
    
func CreateActionArtifactTable(x *xorm.Engine) error {
	// ActionArtifact is a file that is stored in the artifact storage.
	type ActionArtifact struct {
