SCP30: Removed setting

What it does

Reports setting names that have been removed from package versions frozen in your project requirements but do exist in lower versions of those packages.

It also reports the package that defined the setting, the version in which the setting was deprecated, and the version in which it was removed, so that you can check the corresponging release notes for sunset guidance.

Sometimes sunset guidance is also provided in the error message.

Why is this bad?

Removed settings have stopped working the way they used to, and instead are silently ignored.
