WIP: Bzlmod part the one hundred twenty-ninth

Restoring `junit/junit.bzl` and Scala 2.11 artifacts to match
"Add new rules_java preamble to all WORKSPACE files"
(commit 7f746d9).

There's no real need for these files to be different. I'm reverting
them to an earlier state to facilitate convergence between what lands on
`master` and this `bzlmod` working branch.
