RFR: 2331: Improve review notes [v2]

[Pavel Rappo]

> There are two variants of a note that can be added to an item in the "Reviewers" list of a PR body:
> 
>   - 🔄 Re-review required ...
>   - ⚠️ Review applies to ...
> 
> That note may confuse or draw unneeded attention to the PR body.
> 
> Firstly, as a result of recently integrated [SKARA-2312][], "⚠️ Review applies to ..." is also added to an item (i.e. review) that applies to the head of the PR. Secondly, "🔄 Re-review required (review applies to ..." may be present for some items even though a PR has the green "ready" label.
