Add adaptive cards message formatting and unit tests

- Introduced new adaptive cards message formatting in , including functions to format various message blocks such as headers, lines, facts, and expandable sections.
- Created a new  function to generate adaptive card structures based on message body input.
- Added comprehensive unit tests in  to validate formatting functionality, covering scenarios like colored headers, text styles, bullet lists, and expandable blocks.
- Included expected output JSON files for various test cases to ensure accurate formatting results.
