Chatbot: "New Chat" action button location

[kaylachumley]

the new chat button needs to be relocated to a more obvious location. Option to move this to the chatbot header. Explore icon and tooltip.

• what happens when a new chat is initiated?
• Does the old chat becoming archived to the chat history drawer?
• Does a divider/separator appear to differentiate the old convo ending and and new conversation beginning?

@andrew-ronaldson could you take a look at these examples and let me know your thoughts on this? tried a few locations and tried a few different icons. personally I am leaning towards the pen and paper icon for a new message. https://www.figma.com/design/MSr6kVEOuAxmPOkjg7x8PO/branch/56o45rodww3blxSgDN9gDJ/PatternFly-6--Patterns---Extensions?m=auto&node-id=8863-19633&t=nXEnyL4TVJuuaii3-1
