我在npm workspaces monorepo里面写一个vs代码扩展，当我尝试用vsce package打包它时，我得到这个错误：

This extension consists of <files_count> files, out of which <files_count> are JavaScript files. For performance reasons, you should bundle your extension: https://aka.ms/vscode-bundle-extension . You should also exclude unnecessary files by adding them to your .vscodeignore: https://aka.ms/vscode-vscodeignore

我已经在使用.vscodeignore文件，似乎vsce package命令试图获取monorepo内项目文件夹之外的文件
我的目标是获取只包含扩展代码的.vsix文件
