Add a url param to specify dark mode?

[David Alayachew]

Thanks for the response Hannes.

Then I vote that we default to system settings. That is what their system
is requesting, after all. The fact that we ignored it historically seems to
be a weak justification to ignore what is actively being requested
now. Having the default be system settings makes more sense imo.

And it's not like browsers or OS' are defaulting to Dark Mode -- that's
something you have to opt-in to. So, the javadoc website is merely marching
to the beat set by the user's choice on the OS/Browser.

But if you still disagree, then that's fine. Turns out there are different
extensions that can do this for me anyways. Even on my fully locked down
browser, it looks like I can download Dark Reader for Firefox, allowing me
to fix my problem.
