fix: Add style prop to Bullet component

[aharwood9]

🎯 Goal

Style was never added to Bullet so was always using the default defaultMarkdownStyles. This closes #2007

🛠 Implementation details

• Pass the correct markdown style to the Bullet component
• Updated Bullet and ListRow to use the main style object as that already has all the defaultMarkdownStyles and then allows for full customisation.

🧪 Testing

• Open the Sample App, send a message that contains an ordered or unordered list
• See you have all the default markdown styles
• Update the useStreamChatTheme to provide a custom colour to the list
• See the list is now updated with the custom colour

Happy to revert to the part that enforces that listRow and bullet always override the custom styles, but felt like this gives us the power to change these if we have a use-case 👍 i.e. change the fontWeight of an ordered list
