Update Types to allow an array of CSSRuleObjects

[moshie]

When generating tailwind css to js using prejss it combines sections in an array which tailwind's types are not happy with.

"@supports (color: oklch(0% 0 0))": [
      {
        ".btn": {
          "backgroundColor": "var(--btn-color, var(--zui-primary-button))",
          "borderColor": "var(--btn-color, var(--zui-primary-button))"
        }
      },
      {
        ".btn-primary": {
          "-BtnColor": "var(--primary-button)"
        }
      }
    ],

I propose we update the type to allow for CSSRuleObjects[]
