Add dark mode

[astrojuanlu]

It would be cool to have a dark mode in Orchest!

In the same way users can choose a light or dark theme when reading the docs, it would be cool to have a theme switcher in Orchest as well.

[astrojuanlu]

Awesome @himanshukandpal-28! How do you plan to tackle the task? When do you plan to work on this? Anything you need to know from us that you could not figure out?

Note to everyone else, feel free to pick this issue up if it sounds exciting to you!
