Feature and motivation

Request:
I want dark mode on the selenium grid and i think the selenium grid should follow system preferences on that.

Reason:
I embed the grid session in my grafana dashboard that shows other selenium metrics such as browser consumption, queue and limit and it looks really wonky when grafana is in dark mode. Light mode in grafana just looks plain awful so i'd prefer if i don't have to set it to that. :D

Usage example

In light mode

In dark mode where i'd like selenium grid to follow the system preference.
