window.autoDetectColorScheme referenced in workbench.colorTheme setting does not exist

[chroberino]

Bug Description:

The configuration settings for workbench.colorTheme in Theia contain a reference to window.autoDetectColorScheme, which does not appear to exist in Theia:

'workbench.colorTheme': {
    type: 'string',
    enum: ['dark', 'light', 'hc-theia'],
    enumItemLabels: ['Dark (Theia)', 'Light (Theia)', 'High Contrast (Theia)'],
    default: DefaultTheme.defaultForOSTheme(FrontendApplicationConfigProvider.get().defaultTheme),
    description: nls.localizeByDefault('Specifies the color theme used in the workbench when {0} is not enabled.', '`#window.autoDetectColorScheme#`')
}

In VS Code, window.autoDetectColorScheme is used to automatically switch between light and dark themes based on the OS setting. However, Theia does not currently expose this property.

• Is there a plan to implement window.autoDetectColorScheme in Theia?
• If not, should the description of workbench.colorTheme be updated to remove this reference?

Steps to Reproduce:

1. Open Theia's settings.
2. Locate the workbench.colorTheme setting.
3. Notice that the description references window.autoDetectColorScheme, which does not exist.

Additional Information

• Operating System: Windows 10
• Theia Version: 1.58.3

It probably makes sense to have this as a follow up of #15037.

I don't see much value in the window.autoDetectColorScheme option, especially because it's disabled by default.
I would suggest to change the description.
