fix: Fix invalid ngettext usage

[last-partizan]

Description

Format should be called after ngettext, not before.

See example: https://docs.djangoproject.com/en/5.1/topics/i18n/translation/#pluralization

Formatting changes is because i don't know how to properly format it with your previous style, and there's no included autoformat/or formatting linter. I just formatted it automatically with ruff-lsp. Feel free to revert fomatting changes to your style or explain me what to do.

can you please share the output of before and after this change?

That's very good question, because it got me thinking... And turns out, I missed important detail.

In our production code, we override this class with

            extra = ngettext(
                "Try again later in about {wait} second",
                "Try again later in about {wait} seconds",
                wait,
            ).format(wait=wait)

To fix, invalid usage of "second[s]" in languages with three plural forms (like Ukrainian or Russian). I don't see translations for this string in current DRF, and English has only two plural forms, so there would be no changes at all.

Proper way to fix it, would be the same, and i'm pushing updated changes.

Expected changes in Ukrainian, after this change lands, after updating .po with makemessages and after translations added:

-"Спробуйте ще раз через 5 секунди"
+"Спробуйте ще раз через 5 секунд"

Because we have three plural forms:

• (singular, 1) - "секунда", or in this case "секунду"
• (plural 2-4) - "секунди"
• (plural 5-9) - "секунд"
