withData does not take Nullable types

[Hydragyrum]

I have a use case where I with to pass a List<String?> in the withData function. However, the function requires a non-nullable type
TypeVariable<T>

eg:

val listOfData = listOf(
  "one",
  "two",
  null
)
withData<String?>({ "Test with $it"}, listOfData) { string ->
  // Test code here
}

A workaround is to create a holder class which takes a Nullable type, but it's somewhat awkward.

For example:

@JvmInline
value class NullableStringHolder(val value: String?) {
  override fun toString(): String {
    return "[$value]"
  }
}

and use that

val listOfData = listOf(
  NullableStringHolder("one"),
  NullableStringHolder("two"),
  NullableStringHolder(null)
)
withData<NullableStringHolder>({ "Test with $it"}, listOfData) { string ->
  // Test code here
}

This creates a lot of unnecessary boilerplate
