Missing publisher name when running 'vsce package'

[jgentes]

I use WSL2 on Windows 10 and have node / npm installed in Ubuntu 20, not on Windows:

 ~/boss - [master] $ npm i -g vsce
/home/jgentes/.nvm/versions/node/v12.18.0/bin/vsce -> /home/jgentes/.nvm/versions/node/v12.18.0/lib/node_modules/vsce/out/vsce
+ vsce@1.77.0
added 67 packages from 81 contributors in 5.425s

 ~/boss - [master] $ vsce package
