Story

As a user of RHDH,
I want the Side Menu labels (e.g., Clusters, RBAC, Docs, Tech Radar) to support translations,
so that the navigation is displayed in my preferred language and I can easily understand and explore the platform.

Background

Currently, Side Menu labels are defined in dynamic-plugins.default.yaml like this:

menuItem:
  icon: ocmIcon
  text: Clusters

menuItem:
  icon: bulkImportIcon
  text: Bulk import

menuItem:
  icon: docs
  text: Docs

menuItem:
  icon: rbacIcon
  text: RBAC

menuItem:
  icon: lighthouse
  text: Lighthouse

menuItem:
  icon: techRadar
  text: Tech Radar

menuItem:
  icon: orchestratorIcon
  text: Orchestrator

menuItem:
  icon: adoptionInsightsIcon
  text: Adoption Insights

These labels (text) are hardcoded strings and cannot be localized. By introducing support for textKey (translation key) along with fallback to text, we enable proper i18n without breaking existing configs.

Acceptance Criteria

• Side Menu supports both text (string) and textKey (translation reference).
• If textKey exists → use translated value.
• If textKey is missing → fallback to text
• User should be able to provide translation for newly added sidebar menuItem through app-config.The key they can provide through titleKey and translation they should be able to provide through override.json files.
  In app-config.yaml

          default.favorites:  
            icon: favorite  
            title: Favorites  
            titleKey: menuItem.favorites
  

• Add Localization support for Default MenuItems
• Add Localization support For Sidebar Menu strings Like Settings coming from Backstage Translation.
• Add Localization Support for string like Search that is part of Sidebar coming from Backstage Translation.
• Add Localization Support for the a11y Labels used in Sidebar

upstream documentation updates (design docs, release notes etc)
