Support slots.clearButton in <Textarea> component

[stefantschierschke]

I’d love to request support for a small but important feature:

Feature Request
Allow the <Textarea /> component to accept a slots.clearButton prop, similar to how does.

Why it's needed
HeroUI's Input already allows us to override the default clear icon via:

slots={{ clearButton: () => }}

But Textarea does not currently expose the same slot. For design systems where clear buttons have to follow brand iconography or accessibility specs, it's important to control how the clear action is visually represented.

Proposed API

<Textarea
  isClearable
  onClear={...}
  slots={{
    clearButton: () => <CustomClearIcon />
  }}
/>

This would be 100% consistent with the Input component and greatly appreciated in theming-heavy setups.

Thanks!
Really appreciate your time and effort maintaining this amazing library!
