Problem with implementation of logo display in dark and light modes

## Description:

The project currently does not provide for proper display of the logo in dark and light modes. In the original code, the same logo is displayed regardless of the mode selected by the user.

## The relevant code is as follows:

```astro
<div class='flex flex-shrink-0 items-center'>
  <img class='block h-8 w-8 dark:bg-gray-100' src={Logo.src} alt='Logo' />
</div>
