Rename/Fix revoke/restore endpoints

In web-vault v2022.9.x it seems the endpoints changed.
 - activate > restore
 - deactivate > revoke

This PR adds those endpoints and renames the functions.
It also keeps the previous endpoints for now to be compatible with
previous vault verions for now, just in case.
