Scala 2.13.9 & 2.12.16 are dropping support for ?

[SethTisue]

@smarter's scala/scala#10005 and scala/scala#9990 mean that on 2.13.9 and 2.12.16, the remaining tests that test ? aren't going to work anymore

the easiest thing to do would be to just get rid of those tests, since folks ought to migrate to *

it would also be possible to make them conditional on Scala version.

you can see the tests failing to compile at https://scala-ci.typesafe.com/job/scala-2.12.x-jdk8-integrate-community-build/7337/artifact/logs/kind-projector-build.log

first error:

[kind-projector] [error] /home/jenkins/workspace/scala-2.12.x-jdk8-integrate-community-build/target-0.9.17/project-builds/kind-projector-4d8439fb514a46a4de301f2cbcc7015c3143171d/src/test/scala/test.scala:17:7: Either[Int, _] takes no type parameters, expected: one
[kind-projector] [error]   bar[Either[Int, ?]]
[kind-projector] [error]       ^

I'm sorry. I got confused. This was already handled in #186.

(The Scala 2.12 community build is using an older commit of kind-projector, predating #186.)
