refactor: migrated TransaltionBanner

[ameeetgaikwad]

Description

• This PR continues our migration from Chakra UI to Tailwind CSS by updating the TranslationBanner component. Key changes include:
• Replaced Chakra UI components (Box, CloseButton, Flex, Heading) with native HTML elements styled with Tailwind CSS
• Migrated from ButtonLink to the new Button component with asChild prop
• Updated styling to match existing design using Tailwind classes
• Removed Chakra-specific hooks (useToken)
• Simplified conditional rendering using early return pattern
• Maintained RTL support and existing functionality
• The changes are purely presentational and should maintain the same user experience while reducing our dependency on Chakra UI.
