Send "Data project created" notification to admins/curators

[adam3smith]

The system already automatically emails dataset creators. It'd be useful to also send this to curators/admins so we know when people start working on a deposit

I made an initial implementation of this that emails anyone who can publish the new dataset (except the creator who already gets an email). It doesn't add a notification in the UI and is not internationalized, only happens for newly created datasets and not harvested or imported ones. It is also 'always on' with no option to not email people. If we want notifications as well, and/or we want this to be something the community could use, it would take a little redesign and I assume the community would want an option flag to turn it on.

There's at least 3 interested groups there, so let's take the time to put this into a PR

IQSS#8070 created. The changes in that PR are in the QDR branch as well - basically it adds a user notification in the UI along with the email and all of the strings for the email title/body are now i18n/easy to change. Deployed on dev/stage.
