IDE shows correctly picks the theme based on the OS' theme, but it's incorrectly shown in the `Settings`

[kittaakos]

Describe the problem

When I start the IDE for the first time and have a dark theme enabled, the IDE correctly comes up with the Dark (Arduino) theme, but the Light (Arduino) theme is shown in the Settings.

To reproduce

• Mimic a first start, (delete ~/.arduinoIDE/settings.json and execute localStorage.clear() or equivalent)
• Have an OS dark theme,
• Start the IDE, (IDE starts with the dark theme ✅ )
• Open the Settings, it shows the light theme 🐛

Expected behavior

The dark theme is selected.

Here is another problem, after the first start, open the preferences (it shows the light theme as described above), increase the UI scale, decrease it, press OK, IDE theme changes to light.
