# Fix Command Component issues and update documentation

## Changes
- Resolve Command Component issues by wrapping `<CommandGroup />` inside `<CommandList>`
- Update deprecated docs in `combobox.mdx` to reflect latest `<Command />` component usage

### Code Changes

<Command>
  ...
  <CommandGroup>
    ...
  </CommandGroup>
</Command>
```
To:
```tsx
<Command>
  ...
  <CommandList>
    <CommandGroup>
      ...
    </CommandGroup>
  </CommandList>
</Command>
```
