Fix missing translation keys for blocking dependencies in UI (#61314)

[SakshamSinghal20]

This PR resolves an issue where translation keys for "Blocking Dependencies" in the Task Instance Details panel were missing (e.g., dag.blockingDeps.title, dag.blockingDeps.dependency), displaying raw keys instead of the localized text.

The dag and tasks translation files existed in the locales directory but were not registered in the i18n configuration (config.ts), preventing them from being loaded. This change adds both namespaces to the configuration to ensure the translations are applied correctly.

closes: #61314

Thanks for the PR! However, I think the current changes do not seem to address the root cause.

The issue is that the BlockingDeps component needs to load the dag namespace to access the keys in airflow-core/src/airflow/ui/public/i18n/locales/en/dag.json.

To fix this, please revert the changes in this PR and instead modify BlockingDeps.tsx as follows:

1. Update the hook to load the namespace:

const { t: translate } = useTranslation("dag");

2. Remove the dag. prefix from the keys (since we are already in the dag namespace):

// Change this:
{translate("dag.blockingDeps.title")}
// To this:
{translate("blockingDeps.title")}

(Please apply this pattern to dependency and reason headers as well.)
