feature: Alternating background in rendered table rows

Is your feature request related to a problem? Please describe.

I'm loving the plugin overall and the only missing part for me is that table rows are a little hard to visually parse for me

Describe the solution you'd like

I know that adding horizontal lines between rows is not acceptable https://github.com/MeanderingProgrammer/render-markdown.nvim/issues/295 but as an alternative I'd like to propose ability to set alternating background color for the table rows.

I'd be willing to try to implement this feature with minimal guidance where should I look in the code.

Describe alternatives you've considered

currently I'm rendering the markdown in the browser when looking into the tables which is not ideal ;)

Empieza localizando el código responsable de renderizar las filas de las tablas y la configuración existente o el manejo del resaltado de las tablas. Comprueba cómo la posición de una fila puede determinar su fondo e identifica cualquier prueba relevante. Se considera terminado cuando los usuarios pueden configurar fondos alternos para las filas sin añadir líneas horizontales.
