add discovery.datasets to _otel packages owned by infraobs

[mykola-elastic]

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

• apache_otel
• iis_otel
• mysql_otel
• nginx_otel
• nginx_ingress_controller_otel
• postgresql_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.

Checklist

• I have added an entry to my package's changelog.yml file.
• I have verified that Kibana version constraints are current according to guidelines.
• add discovery.datasets to packages
• test if the packages get auto-installed on the data ingestion

How to test this PR locally

• build any of the packages listed (for example, mysql_otel)
• spin up local elastic stack 9.2
• set up OTel receiver + exporter (for example, mysqlreceiver), and the corresponding service (I spinned up mysql in docker)
• check that data is ingested (for mysql - data_stream.dataset: mysqlreceiver.otel)
• wait 5 mins
• check that the corresponding package was installed (dashboard added)

@ishleenk17 this one is ready

[ishleenk17]

I would hold back on this one for now.
As we are still in process of finalizing how we would want to handle the logs Content Packs

[ishleenk17]

1. Can we also add this was tested for which all packages.
2. Pelase create another PR to the othe CP's as well which are not owned by us. Lets track both under the main issue

[mykola-elastic]

I tested mysql_otel, nginx_otel, and postgresql_otel (also aws_vpcflow_otel).

Should I remove nginx_ingress_controller_otel from this one? @ishleenk17

Should I remove nginx_ingress_controller_otel from this one? @ishleenk17

Yes, lets remove it for now. And make a note in the main issue.

[mykola-elastic]

@ishleenk17 I removed nginx_ingress_controller_otel from this one. We can merge it (please approve). I am going to create PR for other packages now (not owned by us)
