[Add] improve the light and dark button on the navbar

Details

I propose replacing the current light and dark mode buttons with a toggle switch with the same signs, I think it would look more engaging.

@Souravvmishra What do you think

[Souravvmishra]

We're good with the current one

@Souravvmishra Is there anything else that can be worked upon, like you guys have stopped accepting any button contributions so like what can we do to contribute now because the three issues I though would be substantial to the project have been closed as unplanned so please suggest something I can do from side
