Backport #24536 by @sillyguodong
close#24449
The unit of `Actions` should be contorlled not only by
`repository.DISABLED_REPO_UNITS` but also by `actions.ENABLED`
in the `app.ini`.
Previously, the permission of the team's `Actions` unit was not
controlled by `actions.Enabled`. So, even if the user sets
`actions.Enabled` to false, he can still select the permission of the
`Actions` unit for the team.
This PR makes the permissions of the team's `Actions` unit also
controlled by `actions.Enabled`. Just append`TypeActions` into
`DisabledRepoUnits` slice when initializing if `actions.Enabled` is
false.
### Changes:
If `Actions` is set disbaled in `app.ini`, like below:
```yaml
[actions]
ENABLED = false
```
1. If user try to create/edit a team, will prompt user that `Actions` is
disbaled.
