Release Note

feat(cmd): operator additional info

[nicolaferraro]

This sounds a bit odd to me, because I know that an integration platform can only be associated with only one operator at any point in time, but I think this is the first case where we put operator information on the platform.

I don't see a better option btw, this looks clean.

Failing because some E2E flaky test as reported in #2744. Merging it if there is no objection.
