[fix]: Improve announcement banner design in docs website

[Achanandhi-M]

Current Behavior: The announcement banner is currently displayed in plain white color, which doesn’t catch user attention. It looks out of place compared to the rest of the docs styling.

Expected Behavior: The announcement banner should use the theme colors from the docs site so that it looks consistent, attractive, and easily noticeable for users.

Steps to Reproduce:

1. Open the website where the announcement banner is shown.

2. Observe that the banner appears in plain white.
