Just to test if/how this works.
It now uses "dbp-auth" instead of "translation", which was the i18next default.

We need a separate i18next instance per component instance and
call setOverrides() to override the translations.

Create a new instance with createInstance() and call setOverrides()
with override data to override translations.

See the tests for some examples.

Uses a separate namespace that gets used over the default one, so we can override,
but also remove the overrides again when needed.

This has the problem that all clones have the same store, so this overrides
the translations for all clones and not just the one providing the overrides.

It was missing a provider element
