docs(examples): centralize styles

[jul-lam]

💡 What is the current behavior?

The appearance of the preview examples lacks consistency and varies across different frameworks.

JIRA Ticket: IX-1118 GitHub Issue Number: X

🆕 What is the new behavior?

Styling is now managed through CSS files located in a newly created central package. Logic has been incorporated to optionally display these files in the code preview. Additionally, minor issues in the code preview appearance have been fixed.
