Add a withData() overload that accepts one element about kotest HOT 4 OPEN

Broken on the following issue in kotlin:
https://youtrack.jetbrains.com/issue/KT-66470/False-overload-resolution-ambiguity-when-both-vararg-and-collection-match-with-a-trailing-function-with-a-parameter

from kotest.

You can write a test use list as follows.

import io.kotest.core.spec.style.FunSpec
import io.kotest.datatest.withData

class Tests: FunSpec({
    withData(
        listOf(Triple("a", 2, "aa"))
    ) { (input, count, expected) ->
        // ... //
    }
})

Thank you, that is a good workaround once one is aware of the issue when using one element. My main issue is that I found it unexpected (and unintuitive and undocumented) that the vararg-overload of withData expects at least two elements. So I propose to add an overload that accepts one element:

fun <T> RootScope.withData(first: T, test: suspend ContainerScope.(T) -> Unit) =
    withData(listOf(first), test)

fun <T> RootScope.withData(nameFn: (T) -> String, first: T, test: suspend ContainerScope.(T) -> Unit) =
    withData(nameFn, listOf(first), test)

There's some reason why we cannot add overloaded function that accept only one element.
