fix(amazonq): code blocks with typewriter text inside list items #5201

Problem
- `<span class='typewriter-part>...</span>` shows up in contents within list items.
- Chat card component reordering and update structure is broken sometimes depending on update type.

Solution
- Streaming content component wrapped out from the chat-item-card and builded as a separate component
- Typewriter animation injection removed from the markdown parsing process
- Typewriter animation injection added to node process state with a check if the node type is TEXT, then we're adding the animation wrapper.
