feat: support for rtl and farsi i18n

[ParsaArvanehPA]

• Added support for RTL
• Added Farsi i18n

In the main.ts of the sheets module, change the locale to fa_IR. The process of changing the direction of html is automaticlly handled based on the language passes to locale in main.ts. Please see these:

• changin html dir base on locale
• locales that are rtl should be defined here

🔶Notes: There is still some work that needs to be done to fully support RTL; they are all css related. I will try to fix those in other PRs, since this PR is moslty about adding farsi i18n.
