fixed Please adjust default table-striped color when dark mode is active Fixes

Fixes #39029

Description

The comment suggests that there was a problem related to readability in the Dark mode of a table. In Dark mode, the background might have been too dark, making it difficult for users to distinguish the table text from the background. This lack of contrast can lead to an uncomfortable user experience and hinder accessibility.
so, I have added the table-dark to tables.

By incorporating the table-dark class, developers aim to enhance the user experience, especially when the application is being used in Dark mode. This change promotes accessibility and ensures that users can easily read and interact with the table's content, regardless of the chosen color scheme.

Hey,

Thanks a lot for your contribution. I think your solution, might introduce an issue for the doc in light mode. And it doesn't resolve the issue you mentionned since people still want to use standard tables.
Closing it for #39033. Feel free to debate if you think I've seen it wrong.
