Add simple dark mode to http.server directory list and error pages

Ideas
1

To make the directory lists and error pages of the simple HTTP server from http.server more readable in dark environments, a simple dark mode support using a few lines of CSS could enhance user experience. I propose the following CSS code, which uses white font on black background when requested by the browser:

<style type="text/css">
@media (prefers-color-scheme: dark) {
  body {
    background-color: #000;
    color: #fff;
  }
}
</style>

Hi Marvin, and welcome :slight_smile:

This was opened as issue #95812 and rejected by @storchaka on the basis that http.server does not include any color information and should not, and I agree.

For additional context, it looks like this request was first made in the third-party uploadserver project, whose maintainer suggested opening a Python bug.
