Add Hindi (hi) translation to the admin dashboard

[RAmPAtel007]

he admin dashboard supports 36 languages but not Hindi. A complete, tested translation is ready in medusajs/medusa#17212 · feat(dashboard): add Hindi (hi)… (it followed the admin translation guide and passed the automated review). It was closed by the PR guardrails because it needs an assigned issue, and the issue I opened (medusajs/medusa#17511) was closed because language requests belong in Discussions. Could a maintainer open or reopen an issue for this and assign it to me, so the PR can be linked and reopened? It may also be worth updating the translation guide to explain how translation PRs should work with the new guardrails.
