While writing the docs for automation rules #6072. I found myself writing examples to no match a pattern using a negative lookbehind, that looks complex and not easy to understand.

So I was thinking to have an option: apply action to versions that don't match the pattern. This would be a select box with two options Match/Don't match or No match

This is useful for people that know what versions they don't want to apply the actions. Like never activate versions that have the dev or nightly suffix.
