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

[sg00dwin]

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.
