Pass size and props for the icons

[Bug-Finderr]

I was using the expandIcon variant in my project and noticed something.

On hover, the SearchIcon (lucide-react) was not the right size.

And I could not find a way to pass it via component calling

Hence updating few parts in the components/ui/button.tsx solved the problem.
Raised this issue so that no one else has to face this.

If this was a dumb issue and could've been solved some other already defined way please do share the idea. Else, please assign me this issue, I'll be able to solve it
