Add dark mode

[nidhi752]

Description

Adding a dark mode theme enables users to have a more comfortable viewing experience, especially in low-light conditions or during nighttime use. It reduces eye strain by lowering the overall brightness of the screen and can help minimize blue light exposure, which is known to affect sleep patterns. Additionally, dark mode can also improve the readability of content for those who prefer a lower contrast between the text and the background.
