feat(build): add Node.js toolkit support

[jokesterfr]

Description

• Add Node.js support
  • npm
  • pnpm
  • yarn
• PLATFORM becomes an alias of TARGETPLATFORM

How to test

$ PLATFORM=linux/arm64 ./build.sh
❯ docker run -it --rm --entrypoint sh prestashop/prestashop-flashlight:latest
/var/www/html # node -v
v16.16.0
/var/www/html # npm -v
8.11.0
/var/www/html # yarn -v
1.22.21
/var/www/html # pnpm -v
8.11.0

Warnings

• PS 1.6 does not require Node.js, and this is better like this because the old Alpine image provided by PHP cannot really ship it correctly (Alpine + ARM64 at least).
