[14.0][FIX] hr_employee_birthay_mail: res_users configurable

[JoanSForgeFlow]

This PR allows each user to grant permission for anniversary notifications from "My profile", otherwise only HR administrators can edit it.

The group "hr.group_hr_user" is also added. Without this group, the open attendances at that time fail and do not allow the attendance session to be closed.
