Add support for customizing search field styles in the Transfer component

[obycapital]

Description:

Currently, the Transfer component does not support direct customization of the search input field styles, such as text color in dark mode. Adding support for the listStyle parameter or an equivalent would allow users to pass custom styles to the search input field and related elements.

Proposed Solution:

Add a listStyle parameter to the transfer function.
Ensure the parameter is correctly passed to the underlying Ant Design Transfer component.

Example Usage:

transfer(..., listStyle={'color': 'white'})

Benefits:

Improved flexibility for UI customization.
Better adaptability to different themes, especially in dark mode.

Thank you for maintaining this excellent library! 🚀😊

Great work overall!
Although the related pull request could be very useful for many people, I just wish that the default search text color is changed in dark mode:

Is it something that could be easily updated, by any chance?
Thanks
