Comments Pagination: Remove unwanted bottom margin from links

[iamtakashi]

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?

This margin appears to have been there since the block itself was added: #36872

@cbravobernal If you know why this margin was necessary, I would appreciate it if you could tell us 🙏

To be honest I do not remember. I guess I copied the styles that were on the non-block version.

I'm starting to think that the ideal solution to this problem would be to deprecate the Comments Pagination block. See #64318 for more details.

Update: Deprecating the Comments Pagination block might not be a good idea, see this comment. Therefore, it would be better to move this issue forward (remove the margin).
