Wrong keyword ability hints (Menace, Scry and other)

Keyword abilities can have special hint text with ability description. But some cards don't have that hint. It uses only ability keyword.
* Menace (This creature can't be blocked except by two or more creatures.) (example: [Belle of the Brawl](https://scryfall.com/card/eld/78/belle-of-the-brawl))
* Menace (example: [Alley Strangler](https://scryfall.com/card/aer/52/alley-strangler))

TODO:
* [x] `MenaceAbility`
* [x] `ScryEffect`
* [ ] Improve singleton abilities to support different settings, see #6731;

I improved `verifyCards` unit test to find that problems. Find that text and enable it to see full list of wrong cards. Current wrong list includes ~200 cards. It can be improved by new keywords later:
* `TODO: enable and fix all problems with effect and ability hints`

How to fix: change ability's constructor param to enable or disable hint:

P.S. Verify tests compare xmage's cards with [mtgjson](https://mtgjson.com/)'s data (scryfall and other).
