refactor(task-drawer): update tab behavior and enhance link handling in description editor

- Changed tab component property from 'destroyInactiveTabPane' to 'destroyOnHidden' for improved tab management.
- Added CSS styles for links in the description editor to enhance visibility based on theme mode.
- Implemented link click handling to open links in a new tab while preventing default editor behavior, improving user experience.
