feat: Persian language support added

[CodeWithEmad]

Description:
this PR will add support for Persain Language (fa_IR) to the project.
as I mentioned here right now we translated all edx-platform's components to Persian but when I wanted to add translations to the Microfronteds, RTL was not supported for fa-ir, so here we are :)

Merge checklist:

• Consider running your code modifications in the included example app within frontend-platform. This can be done by running npm start and opening http://localhost:8080.
• Consider testing your code modifications in another local micro-frontend using local aliases configured via the module.config.js file in frontend-build.
• Verify your commit title/body conforms to the conventional commits format (e.g., fix, feat) and is appropriate for your code change. Consider whether your code is a breaking change, and modify your commit accordingly.

Post merge:

• After the build finishes for the merged commit, verify the new release has been pushed to NPM.

@BbrSofiane or @arbrandes would either of you be up for reviewing this as Core Contributors on this repo? This one is very tiny, though there are also some related PRs with actual translations like openedx/frontend-app-learning#989 openedx/frontend-app-account#666 which may take more time to review.
