Upgrade Bazel container to Java 11 or higher

[lruellan]

Hi,

Recently, my builds on Google Cloud Build that use gcr.io/bazel-public/bazel started failing when processing rules_jvm_external. Someone pointed out that rules_jvm_external no longer supports Java 8. But it looks like the Bazel container includes Java 8. Is it possible to create a container image of Bazel that uses Java 11 or higher?
