* fix: separate vertical alignment enums for table and section properties
- Introduced `VerticalAlignTable` for table-cell vertical alignment with valid values: `top`, `center`, and `bottom`.
- Added `VerticalAlignSection` for section properties, extending `VerticalAlignTable` with an additional value `both`.
- Marked the original `VerticalAlign` as deprecated for backward compatibility, directing users to the new enums.
- Updated type definitions for better clarity on valid vertical alignments.
* refactor: update vertical alignment imports and types for section and table properties
- Renamed `VerticalAlign` to `VerticalAlignSection` in section properties and `VerticalAlignTable` in table-cell properties for clarity.
- Updated type definitions to reflect the new enum names, ensuring better organization and understanding of vertical alignment options.
- Adjusted related test cases to utilize the new imports and types.
* refactor: update demos to use new enums for table and section properties for vertical alignment
