Attempts to find a counterexample for the single given Law.

Meant to be called from inside a Vitest test suite, perhaps inside some describe() block, but not inside a test()/it() block. For example:

import fc from 'fast-check'
import { Law } from 'effect-ts-laws'
import { testLaw } from 'effect-ts-laws/vitest'
const myLaw = Law(
'law name',
'law note',
fc.integer()
)((a: number) => a === a)
describe('testLaw', () => { testLaw(myLaw) })
// testLaw
// ✓ law name: law note
