Refactor repository transfer (#33211)
- Both have `RejectTransfer` and `CancelTransfer` because the permission checks are not the same. `CancelTransfer` can be done by the doer or those who have admin permission to access this repository. `RejectTransfer` can be done by the receiver user if it's an individual or those who can create repositories if it's an organization. - Some tests are wrong, this PR corrects them. --------- Co-authored-by: wxiaoguang <[email protected]>
