Fix markdown ordered list numbering

[rbren]

This PR fixes the markdown renderer to preserve starting numbers in ordered lists. Previously, all ordered lists would start at 1 regardless of the specified starting number.

Changes

• Modified the ordered list component to pass through all props, including the start attribute

Before

All lists would start at 1:

1. First item
2. Second item

5. This would show as 1.
6. This would show as 2.

After

Lists preserve their starting numbers:

1. First item
2. Second item

5. This shows as 5.
6. This shows as 6.
