"TypeError: Object.fromEntries is not a function" when creating a new locale

[lufte]

I'm following the instructions here to add a new locale, but running npm run generate-langs results in the following error:

lufte@lufte-thinkpad:~/projects/remark42/frontend$ npm run generate-langs

I'm running Node 10, and the README stipulates that I need Node 8 or higher, but it seems that Object.fromEntries is not supported until Node 12.11.

Hi @lufte, you should use node 12.11 or higher. We will change readme, thanks for noticing us. Current version of node is correctly mentioned in package.json

It was not exactly 12.11 in package.json. Now I added actual information in PR.
