Allow for a dark logo variant, ensuring proper visibility on both light and dark themes

[jonatanSoftDesign]

Hello all,

When customising the UI, it is possible to replace the logo with a custom one. Unfortunately for some logo colors, it is necessary to have a dark theme logo variant to ensure the best visibility.

This repo has nice image examples, if I choose one, it will look good only on light theme, if I choose the other one, will look good only on dark theme.

Perhaps something like this could solve the issue (I'm not great with frontend)

body.light .logo-container {
    background-image: url('./assets/logo-light.svg');
}

body.dark .logo-container {
    background-image: url('./assets/logo-dark.svg');
}

Sorry if i made any mistakes by opening this disussion, I followed the guidelines the best I could.

Thank you very much!
