Email notifications containing suggested changes aren't formatted nicely

In this MR comment, gitlab-com/www-gitlab-com!29119 (comment 211355367) Ray made a suggestion. In the email notification I received, the formatting was small, it wasn't labelled as a suggestion and there was no gap between Lucy's change and Ray's suggestion.

Original comment, as rendered in the issue:

What I see in my email (Gmail running in Chrome):

I think the following would improve this:

  • it's not clear that Lucy's change is hers - it probably should be labelled
  • Ray's suggestion should be clearly labelled as such
  • Ray's suggestion should be formatted consistently, including font size and clarity around the actual change
  • There should be a gap between the original change and suggestion
