Pull request overview

This PR removes the NoticesWrapper feature and synchronizes translation-related changes from the upstream repository. The NoticesWrapper component, which integrated with the platform-plugin-notices plugin to redirect users with unacknowledged notices, is being completely removed along with its configuration flag. The PR also includes minor dependency updates and Makefile improvements for translation extensibility.

• Removes NoticesWrapper component and all associated code (component, hooks, API, tests, messages)
• Removes ENABLE_NOTICES configuration from all environment files and config
• Updates frontend dependencies (@edx/frontend-component-header, react-router-dom, and transitive dependencies)
