Hi Felix.

Added the suggested information into the document. Made minor changes to the suggested information.

Also, placed the information towards the beginning of the Automatic Instrumentation section to ensure that the audience is immediately aware of this information when learning about automatic instrumentation.

Draft Link: https://docs-draft-openlibertyio.mqj6zf7jocq.us-south.codeengine.appdomain.cloud/docs/latest/microprofile-telemetry.html

Please review the same and add the Developer Reviewed label if you are happy with the change.

Ramkumar

FYI, there was an issue of mpTelemetry running with InstantOn so we reverting the beta fencing in 23.0.0.11. We are targeting 23.0.0.12 now.

Closing this issue as the content is in the telemetry file, which will get technical and peer review as part of #6776 . The changes in this issue are in the same branch as those updates and will be delivered to vNext when that branch is merged.
