[Fix] Buttons ref props

[WiXSL]

Fixes #11134

How to Test

Create a small wrapper around EditButtonProps (like the one from issue #11134):

import { EditButton, EditButtonProps } from 'react-admin';

type Props = Omit<EditButtonProps, 'label'> & {
  source: string;
  text?: string;
  label?: string;
};

export const EditButtonEx = ({ source, text, ...rest }: Props) => (
  <EditButton {...rest} label={text} />
);

EditButton renders a MUI Button with component={LinkBase} + forwardRef, so its props should be typed as ButtonProps<typeof LinkBase> (not the default button props). This aligns EditButton, CloneButton, and ListButton with the existing pattern used by ShowButton.
