Retrieve the page owner email and display name with Get Content V2 API

Issue Summary

The deprecated Get content API and some other page APIs return the page owner in the ownedBy and lastOwnedBy fields with additional information such as their email and display name. In the REST v2 APIs, there is no additional information but the owner id.

Steps to Reproduce

1. Call the mentioned endpoint and check the response

Expected Results

It should be possible to get a page owner's information such as email and display name.

"history": {
    "lastUpdated": {
        "by": {
            "email": "email1@sth.com",
            "displayName": "displayname1",
            ...
        },
        ... 
    },
    "createdBy": {
        "email": "email2@sth.com",
        "displayName": "displayname2",
        ...
    },
    "ownedBy": {
        "email": "email3@sth.com",
        "displayName": "displayname3",
        ...
    },
    ...
} 

Actual Results

No information about the page owner's additional details except the id.

Workaround

Continue to use V1, which is not a long term solution as these endpoints are marked for deprecation, and the recommended replacement is V2.
