ShortcutGrid: Add internationalization (i18n) support for Shortcut grid component

从 Shortcut.tsx 开始，重点查看第 38–54 行附近现有的硬编码标签以及 ShortcutProps 接口。添加可选标签，同时保留当前的英文默认值，然后验证每个布尔型鼠标操作 prop 都会渲染其可自定义的标签，并保持现有的 ShortcutGrid 用法不变。

Describe the problem

The Shortcut component (used by ShortcutGrid) currently has hardcoded English strings for mouse action labels with no way to internationalize them for applications that need to support multiple languages.

Current hardcoded strings

• "Hover" (line 38 of Shortcut.tsx)

• "Click" (line 45)

• "Right click" (line 48)

• "Drag" (line 51)

• "Drag + Drop" (line 54)

These are rendered inside Label components alongside a MouseIcon when the corresponding boolean props (hover, click, rightClick, drag, dragAndDrop) are set to true.

Proposed solution

Add optional label props for each mouse action to allow customization of all user-facing strings:

export interface ShortcutProps {
  // ... existing props

  /** Custom label for "Hover" mouse action */
  hoverLabel?: string;
  /** Custom label for "Click" mouse action */
  clickLabel?: string;
  /** Custom label for "Right click" mouse action */
  rightClickLabel?: string;
  /** Custom label for "Drag" mouse action */
  dragLabel?: string;
  /** Custom label for "Drag + Drop" mouse action */
  dragAndDropLabel?: string;
}

These would default to the current English strings for backwards compatibility.

Example usage

import { useTranslation } from 'react-i18next';

const MyComponent = () => {
  const { t } = useTranslation();

  return (
    <ShortcutGrid
      shortcuts={[
        {
          keys: ['ctrl'],
          drag: true,
          dragLabel: t('Drag'),
          description: t('Move object'),
        },
        {
          keys: [],
          rightClick: true,
          rightClickLabel: t('Right click'),
          description: t('Open context menu'),
        },
      ]}
    />
  );
};

Impact

Applications using Shortcut or ShortcutGrid that need to support non-English languages currently have to either:

• Accept English-only mouse action labels

• Avoid the boolean mouse action props entirely and lose the MouseIcon + Label badge rendering

• Build their own shortcut component from scratch

This would align ShortcutGrid with other PatternFly components that support i18n.
