Color Picker Popup Is Obscured On "Guides -> Theming -> Creating Dynamic Theme Colors" Documentation On Both v5 and v6

### Current behaviour

Color picker popup is not fully shown. I can't fill the color manually because the input is obscured. This happens for primary, secondary, and tertiary color pickers. I don't know if this happens on another platform, but I'm currently using Firefox 155.0 at the time of writing.

### Expected behaviour

The color picker should be fully shown.

### How to reproduce?

1. Go to **React Native Paper** documentation site (v5 or v6).
2. Navigate to **Guides -> Theming -> Creating Dynamic Theme Colors**.
3. Scroll down to the custom theme builder / color picker section and click any color input.

### Preview

**Primary Color Picker**

**Secondary Color Picker**

**Tertiary Color Picker**

### What have you tried so far?

I was able to show the whole thing by changing the "div" element with "color-picker-popup" class, "position" style to "relative" instead of "absolute". But it also grows the parent "tr" element.

**Modified Element**

Comienza en la página de documentación de React Native Paper para Guides → Theming → Creating Dynamic Theme Colors e inspecciona el constructor de temas personalizado, especialmente el elemento que usa la clase color-picker-popup. Reproduce el problema en Firefox con cada selector de color y, después, verifica que el popup y la entrada manual de color sean completamente visibles sin romper el diseño circundante.
