[fa] Localize tasks/configure-pod-container/configure-pod-initialization.md

**This is a Feature Request**

**What would you like to be added**

Localize `docs/tasks/configure-pod-container/configure-pod-initialization.md`
into Persian (fa).

The Persian localization currently has no content under `docs/tasks/`, so this
page would also need the two section index files that make the section reachable:

- `content/fa/docs/tasks/_index.md`
- `content/fa/docs/tasks/configure-pod-container/_index.md`

Without them, `/fa/docs/tasks/` returns 404 once a page exists underneath it.
This follows the same approach as #55008, which added
`content/fa/docs/setup/best-practices/_index.md` alongside its content page.

**Why is this needed**

There is no Persian translation for this page. Persian is currently at roughly
7% coverage (172 of 2506 pages), and `docs/tasks/` is entirely untranslated.

**Comments**

I would like to work on this — I have the page and both section indexes
prepared locally and will open a PR shortly.

Terminology will follow existing `content/fa` usage rather than introducing new
terms, e.g. «مقداردهی اولیه» for *initialization*, consistent with
`content/fa/docs/setup/production-environment/tools/kubeadm/troubleshooting-kubeadm.md`.
