relative_time helper is broken

[nielsfaber]

Since the 2021.10 update, all translations related to relative_time are broken.

E.g. a call to:

this.hass.localize('ui.components.relative_time.just_now')

Results in ' ' (empty space that is).

Requires an update to match https://github.com/home-assistant/frontend/pull/9481
