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 ;)

Beginne damit, den Code zu finden, der für das Rendern von Tabellenzeilen verantwortlich ist, sowie die bestehende Konfiguration oder Hervorhebungsbehandlung für Tabellen. Prüfe, wie die Position einer Zeile ihren Hintergrund bestimmen kann, und identifiziere alle relevanten Tests. Erledigt ist die Aufgabe, wenn Benutzer abwechselnde Zeilenhintergründe konfigurieren können, ohne horizontale Linien hinzuzufügen.
