I believe the user needs to have three options to select: Light, Dark, and System.
I just saw this on https://monorepo.tools/ and I immediately noticed that Docusaurus could also do the same.
Currently, if a user toggles the theme, it becomes "chosen by the user", and to revert to "chosen by the system", they need to clean cookies, right? Not optimal, I think.
What do you guys think?
