Correct OpenSearch migration instructions

[MoteHue]

Because we set kolla_enable_central_logging: true, kolla_enable_elsticsearch is also set to true, as per the Kayobe defaults:

kolla_enable_elasticsearch: "{{ not kolla_base_distro == 'rocky' and (kolla_enable_central_logging | bool or kolla_enable_osprofiler | bool or kolla_enable_skydive | bool or kolla_enable_monasca | bool) }}"

Update the instructions to disbale Elasticsearch explicitly.

Hmm, shouldn't kolla_enable_elasticsearch evaluate to False for Rocky in the above? And for other distros, in Yoga, they should be using Elastic?

We hit an issue with Ubuntu 😅

We need to run the OpenSearch migration in Yoga prior to upgrading to Zed, regardless of distro. At worst, these instructions give us a redundant instance of enable_opensearch that would be deleted when the default is changed to OpenSearch in Zed anyway. As Dawud said, the instructions are currently wrong for Ubuntu systems

Thanks for clarifying
