Bazel: Restrict jackson-core visibility to ES and plugin API
Bazel: Restrict jackson-core visibility to ES and plugin API

The visibility of jackson-core was already restricted to ES in
I27fc60caf51, but this was undone during merge of stable-2.15 into
master in I69847856636. Re-introduce the visibility constraint to make
sure, that no other parts of gerrit accidentally add the dependency on
jackson-core library.
