Set i18n to load only current language (#4359)

This pull request introduces a minor configuration change to the i18n
setup in the frontend. The change improves language loading behavior by
ensuring only the current language is loaded, which can help optimize
performance and prevent unnecessary resource usage.

* Added the `load: 'currentOnly'` option to the i18n initialization in
`frontend/src/i18n.ts`, so only the current language is loaded.
