scalafix: 0.9.0 -> 0.10.0, completions, setup-hook instead of jdk (#171074)

* scalafix: 0.9.0 -> 0.10.0

Bump scala version 2.12.7 -> 2.13.8 (latest AFAICT), as well.

Prefer hash format that matches what nix outputs these days
for easier updating.

* scalafix: shell completion (bash, zsh)

* scalafix: use setJavaClassPath, drop jdk dep

No need to pull in entire JDK just to use the setup-hook.
