How to use DataForm to create plugin settings pages

[meszarosrob]

The https://developer.wordpress.org/news/2024/03/how-to-use-wordpress-react-components-for-plugin-pages/ is (hopefully) a good intro for anybody who might want to use React for their plugin's settings page.

However, with recent developments in the https://developer.wordpress.org/block-editor/reference-guides/packages/packages-dataviews/, the creation of relatively simple settings pages could also be done using just the DataForm.

I think it would be educational to take the settings page of https://developer.wordpress.org/news/2024/03/how-to-use-wordpress-react-components-for-plugin-pages/ and show how that could be achieved using DataForm.

While there's an overlap with #412, that seems more focused on DataViews and its angle seems different.
