In the case of monocle the name of the package may go form monocle-cats to plain monocle. Can a migration be done for that case?

[fthomas]

@cquiroz If a project depends only on monocle-cats and if there won't be a monocle-cats 2.0 because all of its functionality is in monocle now, Scala Steward won't even attempt to update it. I think it would make people's life easier if you'd provide an empty monocle-cats 2.0 that just depends on monocle. In this case Scala Steward would update the version and run the Scalafix migration.

I opened a separate issue #771

If this issue #655 is a meta issue, I think it would be good to pin issue, so that users can find it easily and we can gather more prospective Scalafix migrations.

PR for the scalacheck migration: #853
