[docs] light/dark mode button missing

[angelhdzdev]

Hello! 👋💙
I don't have the light/dark mode button on Edge, Firefox and Chrome, even after clearing cache.

But it flashes the light mode for 1 second before switching to dark:

Greetings to the team.

Fixed now.

Reopening

Moved to Linux (Kubuntu). Button is gone again, in Brave and Firefox. Cleared cache/cookies.

Closing

Ok, the button is gone on the main page, but in the docs it's present, i can work with that.
