`drive-id` means different things in the documentation/api

According to @rhafer the `{drive-id}`  in [/graph/v1.0/drives/{drive-id}](https://owncloud.dev/libre-graph-api/#/drives/GetDrive) accepts a fileId, spaceid or driveid

While [graph/v1beta1/drives/{driveid}/items/{fileid}/invite](https://owncloud.dev/libre-graph-api/#/drives.permissions/Invite) only works with a driveId

It would be super useful to clarify what is needed where.
