⬆️ electron-packager to 15.1.0 in /script

According to https://www.electronjs.org/blog/apple-silicon,
if arm64 is going to be supported, `electron-packager` should be at least
`15.1.0`
Running npm install seemed to update a bunch of other things

Also language-ruby keeps reverting to 0.72, this seems to fix that.
