Fix WORKSPACE snippet for rules_java 7.x

The `WORKSPACE` snippet in the `README.md` now matches what's currently
in all the other `WORKSPACE` files.

I'd previously included the `rules_java` 8.x statements from my Bazel 8
compatibility branch in the `README.md` changes for `rules_scala` 7.x.
@gergelyfabian tried the previous snippet from bazel-contrib#1703, and it broke his
build:
