Subject: [PATCH] [elasticsearch] use bash for readiness script

This commit set the readiness probe to use bash instead of sh. This is
required for Elasticsearch > 7.16.0 because the Docker image is now
based on Ubuntu instead of CentOS 8, and sh on Ubuntu isn't compatible
with the `if [[ ... -eq .... ]]` statements used in the readiness probe.
