Description

The documented way to turn off the spacing scale (see "Disable the spacing scale" section) is to set settings.spacing.spacingScale.steps to 0.

In VS Code, that now produces the warning:

Value is below the minimum of 1.

I don't think it's directly relevant, but the recently filed #62520 is also about changes to theme.json schema impacting valid spacing values.

Step-by-step reproduction instructions

1. Create a theme.json file
2. Use the following value and observe a warning for the value "0" on line 7 in VS Code

{
	"$schema": "https://schemas.wp.org/trunk/theme.json",
	"version": 2,
	"settings": {
		"spacing": {
			"spacingScale": {
				"steps": 0
			}
		}
	}
}
