Keep table background within rounded corners

[d-claassen]

Context

The thead/tbody backgrounds didnt take the table border radius into account. By applying the background color to the table cells instead, the border corners are now fully visible again.

This can be seen in the RSS advanced settings of the plugin, the Semrush related keyphrase table, and the Storybook of the UI library itself. Its also noticeable in Shopify, MyYoast, and other consuming products.

Summary

This PR can be summarized in the following changelog entry:

• Fixes a bug where table backgrounds in the RSS settings and Semrush related keyphrases tables would expand beyond the rounded corners in Firefox.
• [@yoast/ui-library 0.1.0 other] Applies Table.Head background color styling to the header cell instead of the row. #22709
• [@yoast/ui-library 0.0.1 other] Applies striped table row styling on the cell, instead of the row. #22709
