types: random.arrayElement (and probably others) should support ReadonlyArray

[stefanprobst]

Describe the bug

the new types in 6.0.0-alpha.3 (thanks!) don't handle cases where the DT types allowed ReadonlyArray, e.g. random.arrayElement.

Reproduction

import faker from '@faker-js/faker'

const items = ['one', 'two', 'three'] as const

const pick = faker.random.arrayElement(items)

also note, that the other way around would be fine:
