test: Improve test coverage for fenced code block and list item parsers

Browse Source 
- Added more comprehensive test cases for `parse_fenced_code_block`
  to handle various edge cases and improve reliability.
- Improved tests for `parse_list_item` to cover continuation
  lines, empty lines, and task list items more thoroughly.
- Updated existing tests to use more consistent formatting and
  assertions.  This improves readability and maintainability.
