Description
Currently, to create more than one instance in autowire we need to define a helper case class that wraps target instances (e.g. https://github.com/softwaremill/bootzooka/pull/766/files#diff-a9ca80cae7dddc8a64f16da196fc18bf18aff6cbaa4a996a872c0228d1eaddc5R21)
We should be able to return tupled result instances instead.
Test case:
case class A()
case class B()
object Test {
val tuple = autowire[(A, B)]()
}
val tuple: (A, B) = {
import cats.effect.unsafe.implicits.global
Test.tuple.allocated.unsafeRunSync()._1
}
require(tuple._1 == A())
require(tuple._2 == B())

Research direction
Start at the autowire entry point and inspect how results are currently constructed for multiple instances. Use the Scala example in the issue as the acceptance case, then add or run a focused test showing that autowire(A, B) produces both instances and that the allocated result matches the expected tuple.
