LambdaHackWeek: Add Multi-Language Support

[Julian-dev28]

Please add PRs to the update-P21 branch

Description:
Implement support for multiple languages in the Soroban Example DApp to enhance accessibility for users from different linguistic backgrounds.

Tasks:

1. Identify Key Areas for Translation:

   • Review the Dapp to identify all user-facing text.
   • Create a list of strings that need translation.

2. Choose a Library for Language Support:

   • Research and select a library (e.g., i18next, react-intl) for implementing multi-language support.
   • Integrate the chosen library into the project.

3. Add Translations for at Least Two Languages:

   • Create translation files for the selected languages (e.g., English and Spanish).
   • Populate the files with the translated strings.
   • Ensure context-appropriate translations.

4. Implement Language Switcher:

   • Add a language switcher component to the UI.
   • Ensure that the switcher updates the displayed language in real-time.

5. Test Multi-Language Support:

   • Test the Dapp with different language settings.
   • Ensure that all text is properly translated and displayed.
   • Verify that switching languages does not break the UI.

Expected Outcome:

• The Soroban Example Dapp supports multiple languages.
• Users can switch between languages seamlessly using a language switcher.
• Comprehensive and context-appropriate translations for at least two languages are available.

Why This Is Important:
Adding multi-language support will make the Soroban Example Dapp accessible to a broader audience, enhancing user experience and inclusivity.

Hey @Julian-dev28 , do we have any preferences for the library , I have seen i18next being used at a number of places ?

Thought to ask if we have any preferences over the lib or not.
