Dark theme support (feature-request)

[halws]

Hello,

thanks for very useful extension!

I would like to ask, if it's possible to implement there dark theme or at least made it more dimmer ?

Looks like swagger doesn't have a dark mode yet...I wonder if custom css could be used in the extension to force a dark mode? Something like https://github.com/Amoenus/SwaggerDark/
