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

@Aazme - I think this will probably now fall under https://github.com/cloudnative-pg/postgres-extensions-containers - I haven't verified for sure that the new pg18 feature applies to logical decoding plugins but I think it might

Sounds like @NiccoloFei might be working on this soon
