Improve permission check of packages (#23879)

At first, we have one unified team unit permission which is called
`Team.Authorize` in DB.
But since https://github.com/go-gitea/gitea/pull/17811, we allowed
different units to have different permission.

The old code is only designed for the old version. So after #17811, if
org users have write permission of other units, but have no permission
of packages, they can also get write permission of packages.
