added repositories screen dark mode

[V9vek]

Hey @gaganmalvi 👋🏼
I saw issue #26 regarding dark mode to be implemented in the Repositories Screen when we apply dark mode in our device as a whole
I saw the code of the person assigned to it, but he directly applied the dark mode colors, which will result in Repositories Screen always in dark mode and does not change to light mode when we switch mode of the system

So, I proposing the code for the desired thing that you guys want
Take a look and review the code by checking it on your device

Thanks
