Add new locales to the polaris library (#13995)

Related to :
shop/issues-discover-and-convert#62

**Context**
We want to add 8 new languages: Bulgarian, Greek, Hungarian, Hindi,
Indonesian, Romanian, Russian, and Lithuanian.

**What problem is this PR solving?**
For this PR, we are adding all locales . The main change here was adding
the following locales into translation.yml file to trigger Translation
Platform: bg, el, hi, hu, id, lt, ro, ru.


Note : I have added manual translations now, and added a space on source
file, that should trigger translation through TP and get same
translation added through TP.
