Feature: #104868 - Add color scheme switching
See forge#104868
Description
Options have been added to switch between the available color schemes in TYPO3. A set of buttons for each available color scheme in the user dropdown at the top right and a setting in User Settings.
As the dark color scheme is currently regarded experimental until further notice, color scheme switching logic is
currently hidden behind the UserTS setting
setup..
Impact
Warning
If you don't want the automatic switching and don't include the setup core extension in your environment,
you need to manually disable the feature yourself using the UserTS configuration
setup.!
It is now possible to switch to an automatic, light or dark color scheme for use in the backend.
