feat: update home page

This MR adds a dedicated pipeline for home page updates.

Because at the moment BSP is deployed at the root of the s3 bucket, I set up home page publication under /home directory in s3 so it won't affect BSP files in any way.

Home page has been published on production - https://vocabulary.uncefact.org/home

All requests to https://vocabulary.uncefact.org are being redirected to https://vocabulary.uncefact.org/home

This MR also includes a minor fix for untp vocab generation introduced with !763 (merged)
