Story

As a user of RHDH, I want the Bulk Import plugin to support multiple languages so Users will be able to select their preferred language from settings, with automatic detection based on browser preferences.

Background

Dependencies and Blockers

QE impacted work

Documentation impacted work

Acceptance Criteria

• All user facing text in the plugin (labels, button, heading, placeholders, tooltips, alerts, etc) should be translated.
• Translations should be stored in a namespaced file. for e.g. `en.json, fr.json`.
• The plugin continues to work correctly after translation updates.
• Unit test or snapshot test updated to handle the translated strings.

Additional notes:

• Follow the backstage guidelines when creating keys and messages - https://backstage.io/docs/plugins/internationalization/#guidelines-for-i18n-messages-and-keys
