Fix failing "npm install" due to missing Chromium
When running on an AMD64 container (phpfpm), `npm install` would fail
when installing puppeteer with the following error:
```
npm ERR! code 1
npm ERR! path /var/www/html/node_modules/puppeteer
npm ERR! command failed
npm ERR! command sh -c node install.js
npm ERR! The chromium binary is not available for arm64.
