Fix commits pushed with deploy keys not shown in dashboard (#24521)

Fix #21324

In the current logic, if the `Actor` user is not an admin user, all
activities from private organizations won't be shown even if the `Actor`
user is a member of the organization.

As mentioned in the issue, when using deploy key to make a commit and
push, the activity's `act_user_id` will be the id of the organization so
the activity won't be shown to non-admin users because the visibility of
the organization is private.

https://github.com/go-gitea/gitea/blob/55a57177600028ba8e4a480a08f1ee4d69d219d6/models/activities/action.go#L490-L503

This PR improves this logic so the activities of private organizations
can be shown.
