Exclude Org Owner from `inventory-report` when using `--minimal`

The API call to get the Org Owner is an internal ADO API which means it requires a PAT with Full Access scope. Not all customers are comfortable (or in some cases able) to give a PAT Full Access, especially for a command that should only ever be reading.

That seems to be the only API call that `inventory-report` uses that applies to, so we should exclude it when doing `--minimal`.
