TinyMCE now supports dark mode through js init settings. Can Moodle be updated such that:

• The system TinyMCE preferences includes a panel to configure additional styles beyond light & dark modes
• The user's Editor preferences includes a TinyMCE light/dark/auto/custom color mode option

Color mode options could be:

• Light (default/no theme applied)
• Dark (tinymce's dark mode theme config)
• Auto (light or dark based on system settings)
• Additional custom themes (custom theme integrating with TinyMCE's color theming support)

Dark mode announcement & setup instructions: https://www.tiny.cloud/blog/dark-mode-tinymce-rich-text-editor 

Editor style configuration documentation linked from the announcement page: https://www.tiny.cloud/docs/tinymce/6/add-css-options/#add-css-and-styles-to-the-editor

This is similar to MDL-76517 but that one appears to be considering a scss/themes only approach instead of using preferences that could then toggle the tinymce init. Thanks for your consideration
