Similar to #51299, the Comments Next Page, Comments Previous Page, and Comments Page Numbers blocks have unwanted bottom margins. I don't see why we need them, and they are creating misalignments in themes.

We can't get rid of it in Global Styles in the editor, we can't get rid of it in the theme.json, and the custom CSS is getting overridden by default as well.

Can we just remove the default bottom margin for all three blocks?
