"Identity" complex type missing "email" as a Property in XML

[TheKaur]

We use the v1.0 metadata XML to autogenerate all types for our Graph API usages in golang.
Querying a DriveItem returns an email field in LastModifiedBy and CreatedBy fields (user below) but the same is not being captured by the XML metadata. Can we get it updated for v1.0?
