Jira: (EAI-317) [UI] Rich Links in Chatbot

Changes

• Refactors how we handle references from the API
  • Before: we formatted MessageData.references as markdown & appended to the end of the MessageData.content
  • After: we handle MessageData.references separately from MessageData.content inside of Message.tsx
• TODO - Uses Rich Link components from @lg-chat/rich-links (blocked until LG implementation is complete)
