Move from tailwindcss-dark-mode

[onurusluca]

tailwindcss-dark-mode is not maintained anymore. It would be much better that this is removed from the docs and that a way added to use the built in dark mode detector.

Version that added darkmode to Tailwind:

Thanks! Will update ASAP, but PR is also very welcome for this. 😊

Weird because I updated it two weeks ago to use the latest version: https://tailwindcss.nuxtjs.org/examples/dark-mode

I only need to remove the first sentence which is outdated.

@Atinux Appreciate it!
