Support changing favicon for darkmode. If your system is in darkmode you should see a white brand logo as the favicon
<link id="favicon" rel="shortcut icon" href="./logo.svg" type="image/x-icon" /> <!-- browsers that dont support 'prefers-color-scheme' -->
<link rel="icon" type="image/svg" media="(prefers-color-scheme:dark)" href="./logo_white.svg" /> <!-- darkmode -->
<link rel="icon" type="image/svg" media="(prefers-color-scheme:light)" href="./logo.svg" /> <!-- lightmode -->
