Add wal2json package

[paraddise]

Resolves #104 issue

[ardentperf]

i think this patch modifies the wrong file(s). the patch should be a one-line change to Dockerfile.template and then the CICD scripts will automatically update all of the other Dockerfiles when it runs the daily build. (you can run update.sh manually for local testing.)

cf. #83 and #74

Hey guys, just curious, are you still going to add wal2json into your containers?
