The main issue was the inability to dynamically change the locale in OpenSearch
Dashboards. Currently we need to update config file and i18nrc.json.

This PR allows  users to switch to a different locale (e.g., from English to Chinese)
by appending or modifying the 'i18n-locale' parameter in the URL.

* getAndUpdateLocaleInUrl: If a non-default locale is found, this function reconstructs
the URL with the locale parameter in the correct position.
* updated the ScopedHistory class, allowing it to detect locale changes and trigger reloads
as necessary.
* modify the i18nMixin, which sets up the i18n system during server startup, to register
all available translation files during server startup, not just the current locale.
* update the uiRenderMixin to accept requests for any registered locale and dynamically
load and cache translations for requested locales.
