Allow reviewers to delete suggestions
Originally created by @emmapeel on #17514 (Redmine)
Some suggestions are OK, some you can ‘Accept & edit’, changing the part that is problematic, others are plain wrong.
So, when reviewers are reviewing the suggestions, they should be able to delete the ones that are not good. Otherwise there are many suggestions that are not good and look like pending, but they are not going to be accepted.
In case this is seen as bad, we could make reviewer groups per language
