CDH logo file is unnecessarily large

### What went wrong?

My browser warns me on loading the home page:
> NG0913: An image with src http://localhost:4200/assets/UU-CDH_logo_EN_def_UU_CDH_logo_EN_yellowwhite.jpg has intrinsic file dimensions much larger than its rendered size. This can negatively impact application loading performance. For more information about addressing or disabling this warning, see https://angular.dev/errors/NG0913. Find more at https://angular.dev/errors/NG0913

It's a minor issue, but a solid point (the logo is 2268 x 518px). We should use a low-res version or an SVG file.
