Add tests for enum validation with arrays of boolean values

[otto-ifak]

For the const keyword, there are tests like

JSON-Schema-Test-Suite/tests/draft2020-12/const.json

Line 147 in 589a085

"description": "const with [false] does not match [0]",

This PR adds corresponding tests for enum (for all drafts except draft3).

I'm not sure that these tests are adding anything that this test doesn't already cover.

I suspect that the root of the problem in the linked PR is a zero/false equivalency language issue.

[otto-ifak]

Yes, the linked PR is about Python.
However, as far as I understood, there are many tests related to language specific problems in the test suite like JavaScript properties and so on.

I also think, that the new tests indeed cover more than the empty array [] does. There are actually many of these tests for the const keyword already:

JSON-Schema-Test-Suite/tests/draft2020-12/const.json

Line 147 in 589a085

"description": "const with [false] does not match [0]",

I basically just copied these to enum.

Thanks! These look good.

(Greg I assume the thumbs up is understanding how these fit in now -- so merging)
