Set default copy alert permissions

[Remington Steed]

Copy Alert permissions were added in bug #1768992, but they were not assigned to any permission groups. Currently, staff users can create copy alerts, but they are not able to see what they created (i.e. they don't see any "Existing Alerts" section in the Item Alerts popup).

We should assign the "VIEW_COPY_ALERTS" permission to the "Staff" permission group. Are there other permissions we should assign by default? Bug #1798669 implies that some actions need "ADMIN_COPY_ALERT".

Also, we should do something for those upgrading to Evergreen 3.1:
  - Add the permission in a non-intrusive way?
  - Add a notice in the upgrade script about how to add the permission?
  - At least mention it in the release notes?

There was a small typo(VIEW_COPY_ALERTS instead of VIEW_COPY_ALERT), but otherwise it works! I've pushed a sign-off branch, fixing the typos here: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/khuckins/lp1811442_assign_copy_alert_perms_signoff
