[BUG] Can't disable security plugin sins version 2.12.0

[MarioVerbelen]

On our local opensearch environments (in development environment), we don't need the security plugin
So we are using the option "plugins.security.disabled=true"

until version 2.11.1 this option did hes job, but now on upgrading to 2.12.0 this fails
(tested rollback to fixed version vs latest and the option is fine again)
The issue is probably upstream, but I have to start somewhere

docker logs OpenSearch
Enabling OpenSearch Security Plugin
Enabling execution of install_demo_configuration.sh for OpenSearch Security Plugin
OpenSearch 2.12.0 onwards, the OpenSearch Security Plugin a change that requires an initial password for 'admin' user.
Please define an environment variable 'OPENSEARCH_INITIAL_ADMIN_PASSWORD' with a strong password string.

"plugins.security.disabled=true",
},

Note: For OpenSearch 2.12 and later, DISABLE_SECURITY_PLUGIN when set to true will automatically disable the security demo configuration setup and will no longer require DISABLE_INSTALL_DEMO_CONFIG to be explicitly set.

Nice when I replace this in the docker ENV it is working again as my needs
(tested on 2.12 and 2.13)
plugins.security.disabled: true by DISABLE_SECURITY_PLUGIN=true
