Improve i18n Test Output and Add Detailed Logging

Please verify the following:

• yarn test jest tests pass with new tests, if relevant
• yarn lint eslint checks pass with new code, if relevant
• yarn format:check prettier checks pass with new code, if relevant
• README.md (or relevant documentation) has been updated with your changes
• If this affects functionality there aren't tests for, I manually tested it, including by generating a new app locally if needed (see docs).

Describe your PR

Description:

•	Enhanced the i18n test to provide better output formatting in the terminal.
•	Added a clean and well-structured block output that includes details about total keys defined, total keys used, missing keys, and unused keys.
•	Implemented recursive collection of translation keys using collectKeys() for a more accurate comparison between defined and used keys.
•	The output now appears in a block with clear separation, making it easier to read and debug the results.
•	Adjusted the grep command to handle i18n key extraction more effectively.

Changes:

•	Refactored the i18n test to improve clarity and structure.
•	Introduced a new output format for better readability during test runs.
•	Added detailed comments to explain the logic behind each step in the test.
•	Enhanced error handling for retries during the grep command execution.

This update improves the overall test process for missing or unused translation keys, making it easier to catch issues and understand the results.
