Integrate with scalafix in core sbt-typelevel plugin?

[armanbilge]

Spinning out of #37 (comment).

IIUC this would be very similar to our scalafmt integration:

1. Add a dependency to the sbt-scalafix plugin
2. Add the appropriate checks to CI
3. Add the appropriate steps to the prePR command

Projects would then configure their .scalafix.conf as they see fit (or leave empty).
Examples:

The very popular organize imports rule requires an additional dependency.

ThisBuild / scalafixDependencies += "com.github.liancheng" %% "organize-imports" % "0.5.0"

https://github.com/liancheng/scalafix-organize-imports

Tempting to add this dep automatically in our integration. Of course, the rule would only be activated if added to .scalafix.conf; otherwise, the dep just sits.
