Fix Drive documentation to update the tab where to configure deletion behavior

In https://doc.nuxeo.com/client-apps/nuxeo-drive-sync/#deleting-documents it's written :

Starting with Drive 4.1.0, a local deletion will by default unsynchronize the document, and not remove it from the Platform. Clicking on Change deletion behavior settings in the General tab of the client will allow the user to set it back to a real remote deletion.

 However this General tab seems to have been replaced by the Sync tab where this behavior can be changed now
