Set Java version to fix remote execution builds (#349)

This sets `--java_runtime_version` and `--java_language_version` to fix
remote execution builds that otherwise fail with the error:

```txt
$ bazel build --config=engflow //java/...

ERROR: .../java/com/engflow/notificationqueue/BUILD:37:12:
  While resolving toolchains for target
  //java/com/engflow/notificationqueue:client (e53c356):
  No matching toolchains found for types
  @@bazel_tools//tools/jdk:runtime_toolchain_type.

ERROR: Analysis of target '//java/com/engflow/notificationqueue:client'
  failed; build aborted
```

This affects the other `rules_java`/JVM based targets under `//kotlin`
and `//scala` as well. Local builds continue to pass.
