[Feature Request]: Logo switch depending on theme

[slackerkids]

Feature Description

It'd be great if Publii had a built-in feature that automatically switches the logo based on the user's selected theme (light or dark mode).

I made it with custom css. Like this:

/* Logo for dark theme */
@media (prefers-color-scheme: dark) {
    .logo img {
        content: url('/media/files/logo_white.svg');
    }
}
