docs: Upgrade Guide doesn't put config back

On which page do you see this issue?

https://daisyui.com/docs/upgrade/

Describe the issue

In step 1, part 1 of the upgrade guide, we remove some config v4 DiasyUI config.

module.exports = {
   content: ['./your-files/**/*.{html,js}'],
   // other stuff...
-  daisyui: {
-    themes: ['light', 'dark', 'cupcake'],
-  },
- plugins: [require("daisyui")],
}

Then, in step 2, part 3 (side note - just noticed the steps are misnumbered), we add the DaisyUI plugin to our css file.

@import "tailwindcss";
+ @plugin "daisyui";

At the end of the upgrade guide, we've deleted the themes: ['light', ... config and never put it back. I think the easiest improvement would be to include the themes from the first step as an example of config, with a link to the config docs for more detailed instructions.

@import "tailwindcss";
+ @plugin "daisyui" {
+   themes: light, dark, cupcake;
+ }

Thoughts? I could open a quick PR to improve this if that would be helpful.
