fix: remove whole cover-related div if cover is missing (#175)

* fix: remove whole cover-related div if cover is missing

## Summary

Hi! I'm trying to use this theme, and all my blog posts don't have cover image. In such case, the top of all the ArticlesListItem doesn't match. So I suggest this change to remove the whole cover-related div if `article.cover` is not present.

Let me know what you think :)

* Update pnpm-lock.yaml
