Docker: ES requires disabling security to work

Without this setting, I was getting this issue

```
search_1       | {"@timestamp":"2023-10-19T16:13:29.226Z", "log.level":"ERROR",
"message":"node validation exception\n[1] bootstrap checks failed. You must
address the points described in the following [1] lines before starting
Elasticsearch.\nbootstrap check failure [1] of [1]: The default value for
[xpack.security.enabled] has changed in the current version.  Security features
were implicitly disabled for this node but they would now be enabled, possibly
preventing access to the node. See
https://www.elastic.co/guide/en/elasticsearch/reference/8.10/security-minimal-setup.html

[xpack.security.enabled] to \"false\" in elasticsearch.yml before restarting the
node.", "ecs.version":

```

After disabling it, the search container worked.
