Limitless customization: Edit Your Themes Right in VS Code!

With the arrival of the new version of Hydra Launcher (supernova) I've noticed that many old themes have become outdated and some visual elements no longer fit correctly. My suggestion is to add a button that allows you to load the user's current theme for editing, facilitating the updating process and compatibility with new versions.

In addition, it would be great if the launcher allowed users to edit themes in an external text editor (such as VS Code), so they could tweak and customize more freely. This would also help to create an active community for creating and sharing themes, encouraging continuous improvements and the expansion of Hydra's customization ecosystem.
