Changing a theme color changes all the themes color

[mereshow]

Current Behavior

If you create a new theme, with a new name, and change a color of one of the themes, it changes the corresponding color on all the themes.

Expected Behavior

Each theme should be independent and changing a theme color should only be applied to that theme.

Steps To Reproduce

Go to: Dashboard 2.0 > Theming, clic on "+ Theme". Change a color on one of the themes and save it.

Environment

• Dashboard version: 1.11.1
• Node-RED version: 3.1.10
• Node.js version: v16.20.2
• npm version: 8.19.4
• Platform/OS: NodeRed on Docker (Linux 5.15.0-112-generic x64 LE)
• Browser: Chrome
