add discovery.datasets to docker_otel and kubernetes_otel

[mykola-elastic]

Follow-up PR for #15664, #14770

Adding discovery.datasets field (to support auto-install) for:

• docker_otel
• kubernetes_otel

Increased kibana.version to ^9.2.0 as all those packages use format_version: 3.5.0 which is only supported beginning Kibana 9.2.0.

Proposed commit message

See title.

[mykola-elastic]

The dashboard filter for kubernetes_otel package is data_stream.dataset: *.otel. @elastic/obs-ds-hosted-services Please confirm that I picked the right datasets to detect for auto-install:

  datasets:
    - name: kubeletstatsreceiver.otel
    - name: k8sobjectsreceiver.otel
    - name: k8seventsreceiver.otel
    - name: k8sclusterreceiver.otel

These you figured out from the dashboard ? @mykola-elastic

[mykola-elastic]

@ishleenk17 no, in the dashboard there is only *.otel filter, none of them are specified there. I picked the datasets names from the receiver list in the elastic-agent (EDOT). I also, asked the @elastic/obs-ds-hosted-services team for clarification/checking #15733 (comment)

[gizas]

Mykola you are correct. You can find in the list of receivers also here

Also a comment about logs for kubernetes that go to logs-generic.otel . Do you want also to add this?

[mykola-elastic]

Thanks for confirming!
About generic.otel - I would rather keep only "specialized" names. I guess it is possible to some other data to get that "generic.otel" dataset name which would lead to auto-installation of kubernetes dashboard where there is no kubernetes data
