This field should list people that contributed to the translation, e.g. by fixing errors. The idea behind this field is to properly acknowledge all contributors, while still keeping the list of the original translation authors separate.
This way, the selected theme is kept when changing pages, and for subsequent visits. To prevent flickering, we set the selected theme in a blocking script directly on load. To speed things up further, we now use a `data-theme` attribute instead of classes on the body tag, this way we don't need to wait until the body element is loaded.
