Changes

Bug - Before the change: The tooltip always displayed 'Dark Mode' regardless of the current theme

Please describe.

I have updated the internal logic to dynamically display 'Light Mode' or 'Dark Mode' based on the current theme.

How did you test this code?

Manually tested by:

1. Switching between light/dark modes
2. Verifying Tooltip text updates correctly

1. Hover over the theme toggle button located at the top-right corner of any page.
   Please describe.
