谷歌插件开发，manifest.json配置如下：
{
"manifest_version": 2,
"name": "书签",
"version":"1.0",
"description":"书签",
"icons":{
"128":"img/128.png",
"48":"img/48.png",
"16":"img/16.png"
},
"page_action":{
"default_icon":"img/128.png",
"default_popup":"bookmark.html"
}
}当导入到chrome，提示如下错误：
Manifest version 2 is deprecated, and support will be removed in 2023. See https://developer.chrome.com/blog/mv2-transition/ for more details.
这是因为MV2版本的chrome插件在2023年停止支持。将 manifest_version 的版本号改成 3
