explicitly set ownership on elasticsearch data volume for podman compat

[3nprob]

When running the docker-compose stack using podman, the elasticsearch container crashloops due to lacking permissions on /usr/share/elasticsearch/data.

As workaround, running podman exec -it -u0 headway-pelias-elasticsearch-1 chown 1000:1000 /usr/share/elasticsearch/data fixes this and makes everything run fine.
