Display color picker when editing colors

VS Code version

Godot Tools VS Code extension version

System information

Problem statement

It's extremely inconvenient to edit colors manually, and currently the best way to do so seems to be to switch back to Godot every time and find/create a node with a color dialog, or export every color.

Proposed solution

Add/support a simple color picker for Godot's Color format.

Does VS Code have a built-in color picker control? If not, you may want to check for third-party color picker extensions; some of them might support Godot's Color(R, G, B[, A]) format already.

If there's an extension that works well with GDScript, we could recommend it in the extension's README 🙂

Well, here's quick proof-of-concept:

VSCode's built-in color picker is so bad that I honestly don't see myself using this.

It certainly has room for improvement, but I think many will appreciate the inline color preview next to each Color() declaration.
